I took plan b Feb.14th, finished with second pill on Feb 15th (total of 26 hours after sex) Then Feb.23rd had bleeding with some clots, the bleeding was like a period. Was that in fact my period? Then just to make sure I took a pregnancy test March 20th and it came back negative. Although before that my husband surprised me by telling me he wanted to try for a baby, so we started trying March 8-March 20th. I took a test March 20th like I said before and it was negative, then one March 26th negative also, then March 28th and it was positive. So I guess I'm asking if anyone thinks I got pregnant Feb 14th ( the incident we had and I took plan b) or when we were actually trying? Any help would be appreciated. I also spotted for like a half of an hour for one day 5 days after the positive pregnancy test. What could that have been?
