My periods began on 18th november and I had sex on 20th november, basically period sex. I took i-pill immediately and took i-pill for three continuous days. I stopped bleeding heavily for the next 2 days. Then I again my period began on 29th november and stopped on 3rd december. Now I don?t get why did I have periods again? From last week I started to get cramps on my abdominal area mostly upper area and I even had heartburns. I still get em but lesser than the first day and now I am confused what?s happening, if they are pregnancy symptoms because I am just feeling cramps and not others like I read online. I even took a pregnancy test which said negative but like I google, women took many pregnancy tests for a clearer idea. Now I very much confused whats happening.
