pregnancy test accuracy?
Hi, I have complicated situation and am wondering if anyone can please help! I'm wondering how soon a pregnancy test can detect pregnancy. The box states from the first day you've missed your period, however my period is very irregular and "sensitive" (when I first went off to college I didn't get my period the first 2-3 months) so I'm unsure when to expect it. Ever since high school I've had this problem and gone to the doctor about it, and it's nothing serious. Anyway, I last got my period around the beginning of Jan, but for awhile in early Feb I was sick and ate very little, so I'm afraid that may have stalled my period coming. I've had sex twice since my last period, the most recent was two weeks ago. So since I'm unsure when to expect my period I'm wondering the accuracy of the test. Last night I took a pregnancy test (two weeks after intercourse) and it came out negative, but I don't know how accurate that result is since I don't know if my period is late due to irregularity or prenancy. I'm not on any medication (including birth control) and the test I used was EPT in case that helps. So the basic question I'm asking is can I rest assure that after two weeks of sex that the result was accurate, whether my period is late or not. Please help me out!!!! Thank you!
