My bf and I had sex a few times with the “pull out” method and after that I started my birth control pill. My chest grew within the first week and I stopped the pill and got my period for 2 days. After 1 week I started to take the pill again but my chest is still sore and now im spotting,  I took a test and it said I wasn’t pregnant, but im still afraid that I am for some reason. Its only been 3 weeks.

  Is this even possible??
