Hello. Im a college student. i had sex about a three weeks ago with my boyfriend and to be safe i took the morning after pill the best day. About a week later. i bleed semi heavy for about 6 days which i read was the effect of plan b. we had sex a couple times after but we were always safe and double checked the condoms to make sure none of them broke. Now it's about 5 weeks later and my period is a week and a half late. i've taken 4 pregnancy tests and all have been negative. is there a chance i'm pregnant? i've been watching my body for signs but i'm so paranoid that i'm not sure if i'm making them up or if i actually feel them. plus i've been sick with a cold for a few days so i'm not sure i can trust my body right now. please someone help i need advice and some reassurance.
