Brace yourselves, I'm about to get real personal, I need someone to reassure me. My last period ended on the fourteenth of February. I had protected sex on the sixteenth, and then unprotected on the seventeenth at about one in the morning, but he did not finish inside of me. I took Plan B on the nineteenth just to be safe, so it was about 30ish hours later. It's now the 24th of March and I have not had a period save for the couple days of bleeding from Plan B. Rationally I know the chance of pregnancy is pretty slim, but I'm just nervous because I've taken Plan B once before (bad I know) and I still had my period basically when it should have been. Thoughts?
