Every month up until June I had my regular cycle the 17th -22nd. June it was 12th-17the but still a normal flow. I'm on the pill, had sex one time and that was the day my period ended. Now I'm only having period like blood when I wipe. Nothing on the pad nothing in the toilet. And it's very light. I do have mild cramps today finally. Is this my period? Is it possible I'm pregnant? Has anyone else experienced this? Thanks in advance for the help!!!
