So I had a period May 28-June 2. I had unprotected sex on June 6th and took plan b the day after. I then had unprotected sex again with my fiancé on June 11th and took plan b again that day. i had really heavy bleeding that started June 13-June 18 like a regular period but that would mean I was two weeks early. I then took another pill on June 20th cause the condom broke on June 18th. I had some spotting June 22-June 24. It is Now July 21 and I haven't had any signs of bleeding. I took two pregnancy test and both were negative. Could I still be pregnant or is plan b really messing my cycle up!? Help!!
