well if it worries you, the best thing that you could do is to go into the doctors and explain to them. You probabley do need to tell them about the sex part as well because sometimes it may help them to diagnose the problem. If it is cysts on the overies they will be able to tell through ultrasounds. but if thats not what it is they may need to do further tests. so good luck with it all. but i really do advise you to get it checked out. because the longer you leave it the more problems may arise
