Are Symptoms Pointing to an Ovarian Cyst?

I have been experiencing lower abdomen pain for quite a while. Normally right befor my period. I had a regular obgyn exam in June and nothing was found. i did not tell my doctor about my problems that I was having. It sometimes radiates down my right leg. I have a hard time laying on my right side when I am experienceng this pain. Lately I have been going to the bathroom more than normal. When I have sex, sometines it feels like my husband has hit something and caused a bruise. My periods are starting to become farther apart ( about 35-45 days). I have been going to the doctor regularly to try to get my asthma under control. I do not want to constantly complain about something because I feel like a hypo-condriac. I had pre-cancerous cells removed almost 4 years ago from my cervics. I go for regular paps every six months, they have all been negative. Should I be more concerned? Could this just be a cyst? Ovarian cancer does not run in my family and I am other wise a healthy 34 year old mother.
