Back in early April I found out I was pregnant. When I went for my first appointment, two ultrasounds confirmed there was no heartbeat at 8 weeks and a week later I had a D&C. During both the ultrasounds, they suggested I had a bicornuate uterus with the baby implanted in the left horn. After the D&C in May, I started the birth control pill Aviane. I am now on my fourth pack of Aviane. This month, I missed the very first pill but took two pills the next day. Around this time I did have unprotected sex and have been this month. I haven't missed any other pills and generally take the pill between 9-12pm every night. I started my last period on July 27th (the third placebo pill). This Monday the 16th, I started feeling cramping especially on my left side. Usually, I will feel crampy a couple days to a week before I get my period, but I have never had cramping two weeks before my period. Is this cramping a side effect of the birth control, extra cramping due to a bicornuate uterus, or could I be pregnant?
