On May 24, 3 days after unprotected sex I decided to take a plan b. On June 3rd I started what I thought was my period. It started very light pinkish/Brown spotting and completely stopped 3 days later. (My spotting was only a few times and only when I wiped) My next period was due on the 22nd of June. I had all the typical menstrual symptoms but it never came. When I hit 10 days late I took an at home pg test and it was negative. The next day, July 2nd I started spotting and it became heavier throughout the day. Day 2 moderate bleeding and then day 3 it's completely gone. I'm so confused. Could I still be pregnant? My periods never last less than 4 or 5 days. Sorry for the long post and thanks in advance for your help.
