Chances of preg. according to symptoms.

I had abortion 3 months ago. That time, before my periods were due, I had severe morning sickness where I wasn't able to eat anything. I used to vomit many times a day. My breasts were tender and I had frequent urge to pee. When my periods were due, I started bleeding but the bleeding was light and it passed without any clots. The bleeding continued for 24 hours. After abortion I had an PID with left ovarian cyst. Last month I was sexually active. On the day of ovulation I took unwanted 72. Before few days my periods were due, I had cramps and fever. On the due day, I started bleeding but it passed with clots like normal periods. In between, the bleeding and cramps used to increase and decrease. After 36 hrs, the bleeding stopped but after 8 hrs of stopping, it again started with light bleeding and cramp. Till now, the bleeding hadn't stopped. I don't have breast tenderness, urge to pee. Only little bit feeling of vomiting. Is this pregnancy or can this be ectopic preg. or due to cyst
