Okay, i'm two years out of highschool and was not planning on pregnancy.

About 2-3 weeks ago I got a bacterial infection that later turned into a yeast infection. Around that time, I started feeling bloated as if I were going to start my period. Soon after I got constant headaches and backaches that are still going on. (i have constant dull aches everywhere in my body and i'm still feeling fat)

about 2 weeks ago I started craving salads and chocolate milk. I also became constipated around this time and am still having constipation. I also started getting sharp pains in my abdomen around this time.

About a week ago, I started cramping like I was going to have my period, but I never did. Morning sickness also set in at this time. I don't get sick every day, nor all day... But more like just radomly. It seems like the smallest things take it out of me too. Just doing the dishes makes me feel lightheaded and like I need to sit down. I took a pregnancy test at this time, but it showed up negative.

The other day I was at my fiancees parents house for dinner. My legs started going numb and I couldn't sit in one position for very long. The day after my right leg hurt all day long. I'm still getting numbing feelings in my legs every now and then.

My backaches are constantly nagging me. It hurts so bad that my fiancee can barely even touch it.

My mood swings are horrible! I get so irrate over the smallest things. I'll cry hysterically over nothing. Its usually at night that my mood swings take place.

I've also been getting cold chills alot during the morning and day, but at night i'm so hot that I have to get naked. Sleeping is horrible... I can't get comfortable at all! It takes me 1-2 hours just to fall asleep when it used to take me 10 min!

I took another test today and it again showed negative. I'm now 3 days late for my period but am still having light cramping that comes and goes. I'm on the patch so I normally start my period the day that I take it off or the day after. And my cramps come with my period, not before it.

I got an apt. With the doc. For a blood test. They told me that I could come in anytime within the week. I want to go in today, but i'm afraid of it showing up negative. I don't know what on earth i'm going to think is wrong with me if i'm not pregnant. I just have this feeling that I am though. Womans intuition I guess. I also think that I knew the same night of conception. I had a weird feeling after sex and I had even told my fiancee about it. I don't know.... I feel like i'm going crazy or something!

So... Do you think its too soon to get the blood test done?
