My last period I THINK was around May 25th or 27th and also I stopped taking my birth control pills then. I believe I had sex around the 7th of June, as well as couple other times around the 7th. I haven't gotten my period yet which is not normal because I usually get it around the 24 or 25 of every month. However, for a few days I have had cramping and spotting. It is nothing like a period and seems to come and go a little bit through out the day. I have heard of implantation bleeding and am now worried that this might be that. Is there a way I could be pregnant?
