I'm sorry to hear about whats happened but there's no way of finding out for sure unless you do an amnio and get a dna test done. I'm sure your boyfriend would be supportive and loving if you told him the circumstances under which you might have conceived.
Hope all goes well

I also think like tanya, I mean unless when the baby is born and u did a dna test, but if u waited so long to tell him, he might think u are lying.

So I think it's best if u told him now...Asap!

I am sure what happened is not ur fault, and if he loves u enough, he will understand.

And honey, alone in mexico? No parties for any girl! It's dangerous out there!

Hi there...Well, if you say you are reguler and your periods always come on the 5th of the month, then I would say the 20th would have been right at your ovulation point. I do not know for sure of course. See, usually a person with a regular cycle ovulates right in the middle of cycle...Between 14 and18 days from the first day of your last period. But, I still think you should tell him..Eventually it will come out somehow anyway...And better to be honest from the start and hopefully get support than to suffer alone in silence and worry about it throughout the pregnancy, right? God bless you and I am so sorry for what you went through.

I for got what it was called but my aunt mary had got it done she was sleeping with all types of males until one day she got pregnant she went to the doctor told them what happened. They sent her to another hospital and made her wait until she was 15 or past 15 weeks then stuck a needle through her stomach and got a dna sample from the baby. She found out who the father was she didn't like who here father was put the baby up for adoption. But if want I can call here up and ask her what she did to get an early dna sample of the baby while still in the womb just give me an e-mail I can probley find out. But now you know there is a possible way to find out before the baby is born.

An amniocentesis is where they put the needle through your stomach and take out some amniotic fluid from the sac. However this is painful, and there are some risks involved.

It would be better to find out and tell the father, so the two of you can sit down and sort out what you plan to do for this little helpless being. Me personally I dont suggest and abortion because of what it does to you emotionally to know what you have done, but if that is the best way for you to sort out this problem. Is the guy who inpregnated you, your boyfriend or some one that would be willing to suport you and your baby?? Before you make any decisions talk to him!!
God luck & god bless
