I've been experiancing excessive bleeding during menstration and sharp pains what could it be? I had a c-section 4 years ago and they discovered a lemon sized cyst on my left ovary. They removed it but ever since then I've have horrible pains during menst

You. You need a pelvic ultrasound in order to see if the cysts returned or to see if you are dealing with uterine fibroids, which could be the cause of your pain and menstrual irregularities. There is no reason to be afraid to see your doctor. You will get much needed care and treatment which will ultimately improve your quality of life. Take care.
