I had my last period on August 8. I usually have about a 28-30 day cycle. On August 18 me and my fiance' had protected sex with a condom and he pulled out before ejaculation. We haven't had sex since then, but now my period is 1 day late with no signs of it coming. I took a test yesterday evening,a clearblue digital and it said NOT PREGNANT. Thinking that maybe because I didn't use FMU it turned out negative, I took another test this morning with FMU. Still NOT PREGNANT My breasts are kinda sore, but that's the only sign of my period. It's been 23 days since I had sex, would a test show by now, or should I wait longer? Someone give me some advice please! Has anyone had a similiar experience???
