Hi there. What you have mentioned can be a sign of nodular cyst or ovarian cyst. Do you face any kind of irregularity in your mentrual cycle? Pain and excess bleeding during menses? When does the pain occur? During sex only or even after that? Do you see any kind of bleeding after sex? If so then these are not good signs and you should consult a gyenacologist at once. One other possibility is of fibroids as well. These are serious conditions and often requires surgery. Do not be afraid. You can always talk to gyenacologist in private about your problems. But do not neglect.
