I would like to start of by saying I am a relatively healthy 23 y.o female , who is not, at the moment trying to get pregnant, but has some gynecological issues. I have been on birth control medication from the time I was 13 until October of 2009 (I got my period when I was 11), in the forms of pills, the patch and from July to Oct. of this year, Depo Provera. I have also had the HPV vaccine completed by the time I was 21. Between July and Oct., I had inexplicable intense cramping in my right ovary and lots of pain during sex with my boyfriend (of 7 years). So, I attributed this to side effects of "the shot". Since October, I have not been on any form of birth control medication whatsoever. After a long consultation with my OBGYN/ONC he recommended a pap-smear, breast sono, thyroid sono, abdominal sono, trans-vaginal sonogram, pelvic CT and blood tests all on Nov 13th 2009. All the results of the tests came out completely normal or "unremarkable" with the exception of the Pelvic CT. It was found that I have a small (1.7cm) dermoid cyst in my right ovary [this explained the pain]. Before I state my question, let me note that my last "on-the-pill" period was from July 3-8 '09. After my tests, I started spotting.rom Nov. 18-25, I had at first a heavy, very dark brown then "normal" red, light period. From Nov 26-30 (until the evening), I was period/spotting free. Then from Nov.30 to Dec.9th I had a medium to light "red" period, with the last few days mostly consisting of spotting. From Dec. 10-13th I was spotting/period free and now since the evening on the 13th, I've had almost black spotting to a light flow of blood . I had sex on the 18th and 26th, but not on the 13th so I do not believe it was triggered by intercourse. My question finally is, are these irregular menstrual cycles due to all the years of birth control, the cyst, the shot or something else and will it ever go back to "normal"? If you need more details, feel free to ask. All responses are appreciated.
