Okay so my last period was august 29th and I'm very regular, so my fertile days were the 11th thru the 16th, I'm pretty sure I ovulated the 11th or 12th, I had sex a few times before my fertile and ovulation day and a few days after, its now the 20th and the past 2 to 3 days I've felt funny, I keep getting weird cramps in my pubic area, and been extremely moody, no spotting tho, could this be conception, implamation or something, could I be pregnant? I will add I'm diabetic and was put on a pill called metformin which is also used for something to do with cyst on the ovaries and it regulates women and makes them ovulate regulary and I was told it enhances the chances of becoming pregnant, please I need advices
