On same pill for 2 yrs period was 10 days w/ extreme unusual clotting followed by continuous spotting & cramping for going on 7 days after period end?

Oral bc spotting: Today's bcp's are very low dose, and require taking them punctually or breakthrough bleeding will occur. If the bleeding continues, stop the pill, wait for five days, and start a new package. Take the pill within the hour (in the evening) when you took yesterdays pill to prevent irregular bleeding as you describe. You should get a serum pregnancy test (HCG) to be sure you are not pregnant.

Prolonged bleeding: This could be due to missed pills, breakthrough ovulation, pregnancy complication, cysts, fibroids, polyps or simply an out of the blue bad cycle. You may wish to confer with your gynecologist if bleeding and cramping persists.

Infection: There is something wrong and the most likely thing thing is an infection. You need to see yourPCP or a GYN as soon as possible. Good luck
