Going on day 2 after my period was supposed to start. I took Plan B about 10 days ago and did some research on it and it says it doesn't work on women who are over 176 pounds! I am 200 pounds 5'11" and took it. I was ovulating the day before we had sex, we didn't use a condom, he pulled out and then we had unprotected sex again shortly after. Should I take a pregnancy test?!
