Well I an problem.... I was on the drop shot but stop August 2015 because I wasn't having sexual intercourse. I started back having my periods in July of 2016 and had sex for the first time in two years in September (using the pull out-method)... I had my cycle the next day for five days.... Then October comes no cycle and I took a pregnancy test and it came back negative during the week I'm suppose to be on my period but I am cramping... please help.... and I'm sorry if some words make you feel uncomfortable
