On October 18th I had unprotected sex. 2 hours later I took the Plan B pill. About three days later I had bleeding and cramps for a week and it seemed just like a period. It wasn't spotty, but was a consistent light bleeding for that week. That ended on October 27th. It has been a little bit over 4 weeks since that and I am not sure what that means. For the past couple days I've been having period like cramps, but no bleeding. It feels like how I feel before I get my usual period. I am going to take a pregnancy test, but wanted some opinions as well. Was the bleeding after my Plan B pill my period?
