So I had my last period around September 3 or 4 of 2007 and then I had unprotected sex on the 14th. I took the morning after pill on Monday the 17th. They said I should bleed within 2 weeks and my two weeks are up tomorrow. I started spotting on Friday and still am but its not period bleeding...Its very light and I have major cramps and my breast are kind of tender. I took an at home pregnancy test on Friday but it was negative. Could I be pregnant? Or is it all from the ECP? Please give me some advice and tell me what you think. Thank you.
