So I had sex with my bf on Thursday right after I finish my period like 4 days after and then the next day I took. A plan b but then  Sunday we had sex again and he did not came in me  I was aware that he did not came in me but on Tuesday I started spotting and now it's been 3 days and I'm still bleeding like if I got my period and it's weird because I literally finish my period on 6/28/17 & now I'm bleeding like if I got my period started on 7/4/17 I'm really confused and scared someone give me their opinion:(  is this possible getting your period after a week. Again
