Myrtle Beach, SC
I experienced the same thing, last January. My doctor found a cyst on my left ovary last September. It never bothered me, other than my cycle being out of wack. (I'm going through early menapause at age 36, found out through bloodwork, so that could also add to my freaky cycle). Long story short, I chose to have it removed in January because the pain was getting worse, not better. When my doctor went in (laproscopy), he removed 20cc of fluid where it had drained. It was only about 2 cm in diameter. It was a minor surgery. Having a cyst removed from your ovary will not leave you unable to conceive. Alot of women have cysts on their ovary/ovaries. Most doctors choose not to remove them because they will go away on their own. They shrink and grow according to your hormones and cycle. If it's causing you pain, your doctor will do a vaginal ultrasound to see what/where/how big it is, and if it's leaking.
No matter what, please tell your doctor about your symptoms. And try not to let it worry you.
