In July I had a period issue for which the doctor gave me primolut n. I got a heavy flow of periods on 1st August. In the middle of August I made out with my bf where he rubbed is penis on my vagina for some time. I'm a virgin and haven't had sex before . for precautions I still took emergency contraception. 29th august I started my period which lasted a day and at night I had a brown ish lubricant kind of discharge and throughout the day I had cramps like never before. then next day I had very low flow but periods and then for two days I didn't have proper flow it was just like heavy spotting. Now i don't have spotting or perioids. Is pregnancy possible? If not then why am I facing so many menstrual problems. Of course I'm over weight but I've never had this trouble. My physician gave me glucophage 500mg and told me that I probably have swelling. But I'm scared I might be preg. Help
