Q: Very Fast Home Pregnacy Test Results Concerns/doubt

How soon can the best home pregnacy tests on the market detect pregnacy? Can they detect before a missed period?

Here's the scenario, a lady friend and I engaged in intercourse several times during the weekend of march 4 - 6. Exactly two weeks from the 6th she called me on march 20 saying that she took a home test and it's positive (pregnant result). So, the first question out of my mouth was, "what made you take a test? Did you miss your period?" she says, "no, I just felt like something was wrong. I've been pregnant before and I know what it feels like."

so, after having it confirmed by a doctor this past week monday, march 27, I learned that her last period occurred on feb 24. From my information, since she has a regular cycle, her ovulation date should have been around march 10 - 11. This means that any sperm that would have slipped by would have had to hang around inside of her from the 5/6 to the 10/11. That's 4/5 days. On top of that, although we were irresponsible and didn't use an protection, I still didn't release any sperm (ejaculate) inside of her unless there was some slip up along the way. And of course she's saying that it's only been me.

My question is, (1) if it is me she's pregnant by, could any home pregnacy test detect pregnacy that soon and before the next scheduled period was missed. (2) does it seem likely that she be pregnant by me?

Whomever is qualified to answer, please tell me your credentials. Thanks.

Pregnancy tests are good up to 5 days before your missed period.

Did you go to the doctor with her? How far along did the doctor say she is? It seems unlikely to me that she would know she was pregnant within 2 weeks. You may want to investigate her claims further.

Good luck.

I did go with her to her general practioner. Not an ob-gyn. I didn't think to ask how far along she was at that time, either. The doctor basically asked when her last period was and calculated everything based on what my lady friend verbally told her.

So, I also didn't want to offend the young lady just yet either by questioning whether she was possibly already pregnant.

Why do you say it seems unlikely? What are basing that on? I'm hoping you are a doctor or nurse. Either way, I appreciate your response.

I am neither a doctor or a nurse, I am a woman who has been pregnant multiple times.

Usually the first indication of pregnancy is a missed period and the majority of women do not have any symptoms until then.

What did the doctor do? Generally your first appointment is extensive and filled with urine tests, blood tests, and a check of the size of the uterus.

I could be totally wrong - but you should make sure this is your child. (i'm assuming she is keeping it and wants you to take care of her)

Every woman ovulates at a different time. The average and most common time is 14 days after the first day of her last period. If she ovulates on day 14, that would make her fertile from around march 5 to march 10th. That's a big if. She most definitely could be pregnant and most definitely could have got a positive on a home pregnancy test before her period was due. I know about day 6 or 7 after ovulation if i'm pregnant. Some women can tell.

However...If you did not ejaculate inside of her, it significantly reduces the chance of you making her pregnant. It still is possible, though. I'd suggest supporting her now and getting a paternity test after the baby comes.

Oh, and as far as my credentials, i've been pregnant 3 times and have done much research on pregnancy. I am not officially certified in anything to do with health, though.

I've been pregnant 4 times and have 3 children. I host a birth club and a worry board on .Baby.Center.

Anyway, if you know the date of the 1st day of her last period, count 12-14 days including that day. She would most likely ovulate on day 12, 13 or 14. She could get pregnant from anywhere between days 11-through-18. Sperm can live on average 48 hours but some persistant little buggers can live up to 5 days.

.E.T.A that while new pg tests .C.A.N detect hcg 4 or 5 days before a period should start, they don't always. In my experience, .I've never had a pg test show positive before my period was due. On my last pg it never showed up on a test even days afterwards, .I had to get a blood test.

sorry, but I have to disagree a little. If she ovulates on day 12, then she could get pregnant before day 11, possibly as early as day 8.

All this leads me to continue insisting this man find out if there is a possibility she was already pregnant - because, to me, it seems very convenient.

Hun, you have to note that we aren't doctors we are wemon who are and who have been preggers. We will give you advice and whatever knowledge on the subject that we may have.

All wemon ovulate differently....Average wemon ovulate like 12-14 days after their periods. Some within a few days of their period. I ovulated around 3-6 days after my period. I know this because my husband went to sea the 2 days after my period ended. And we....Well I won't get into that.

You need to understand that the irresponcibility of engaging in unprotected sex may end up in pregnancy. If you have doubts then a paternaty test will be your best bet. That baby may very well be yours unless she entertains a lot of gentlemen during that time.

Btw I found out I was preggers 2 days before missed period.

of course, she wants to keep it and of course she's expecting me to take care of the child. And of course, I don't want to keep it. Why? She has one child (not by me) already, a part-time college student, still lives at home with her mother, and we've only known each for a couple of months. However, she using religious beliefs as her reason for wanting to keep the child although we talked about sex often before it actually happened.

Good luck to you! Please keep up informed about what happens.

You need to date the pregnancy. Maybe an ultrasound?

.No matter her reasons for wanting to keep the baby, you really won't have a say in the final decision. I realize that it seems "religious reasons" weren't enough to keep her from sleeping with you in the first place, but that's no reason to dismiss her using religion as a reason to keep the baby. There could be every reason in the world to not keep the baby. The fact is that she doesn't need a reason to keep it other than "she wants the baby." sorry, that's life and how the law works.

What you need to do now is get an accurate due date from her. It should be right on the ultrasound photo. Then you can try to calculate if the timeline matches up but chances are high that you'll need a paternity test when the baby is born. If she needs an amniocentesis for medical reasons, she could have the paternity test done from that at the same time.

What did they tell her her due date was? I know how to calculate a due date and you can estimate how far along she is from that. Obgyns use that wheel thing and estimate it from the date of a womans last period.

Here I got this off a website
""the approximate date may be obtained by taking the date when your last period began, adding 7 days, then counting back 3 months and add a whole year. For example, if the first day of your last period was september 9, 2000; add 7 days and you get september 16,2000; then count back 3 months and you have june 16: the estimated due date is june 16, 2001""

so if her last period was feb 24th her due date would be december 1st. So right now she'd be 4 weeks along. I dont seem like it adds up. But this is just estimated totally by the date of her last period. Your best bit is when they do the ultrasound they can tell you more accuratly how far along she is. And i'd defantly get a dna test done if I were you.

Just a quick question....Are you rich and she mistaked you for a fool? If this baby isn't yours you don't have to father it. However if it is your's then you need to take the responcibility and take care of the baby.

Don't pressure her into an abortion, just wait for a paternaty test and go from there. You call her a young lady, are you much older than she?

I have a pregnancy wheel that gives the dates of conception based on the day of her last period. (if you go to the obgyn the dr or nurse would use this wheel to determine her due date, then the ultrasound will be more accurate with the measurements of the baby.)

if her period was on feb 24th then according to the wheel her conception date would have been on or around march 10th.

I know that the dr used this wheel on my pregnancy, and with my sister, and friends, but then the ultrasound is more accurate. You may need to wait for the ultrasound, and paternity test.

Sounds to me like she was already pregnant.
I've been pregnant 3 times. Each time I was sure I was pregnant and started testing really early. I've never *ever* gotten a positive result 2 weeks after having sex. *e.V.E.R* it's always taken about 4 weeks to get any test to read positive.
Her saying she "just knew" something was weird seems odd, as it would probably be even too soon for her to feel any symptoms.
I'd find out when the doctor thinks she conceived and go from there.

Yep, I agree with the others. Make sure you take a paternity test when the child is born.

that's actually not true. A lot of women feel symptoms as early as 5 days after conceiving (5 days after having sex). It is uncommon to get a positive pregnancy test earlier than 10 days after conception (10 days after "having sex"), but it has happened. It's very common to get a positive test result 2 weeks after conception.

Yes, I haven't any doubt that pregnancy tests can work as soon as 5 days before your missed period. But I would think that would be if you ovulated early and implantation was quick.

In the real world, this isn't necessarily true. It seems suspicious because he didn't ejaculate inside her (yes I know pregnancy is still possible, but less likely) and that she took a pregnancy test 2 weeks after intercourse. So 3.5 weeks after her period she knew she was pregnant? Fishy.

i think we're going by our knowledge and personal experiences here. All three times I was pregnant I knew 3.5 weeks after my period. I had symptoms and had major symptoms with my last (which ended up being a twin pregnancy) along with implantation bleeding well before two weeks post conception. I know a lot of women get no symptoms, but a lot of women do get symptoms. Also, a lot of women are serial pregnancy test takers and take one at the first inkling (or even every month) or pregnancy.
