Since the age of 18/19 my menstruation has been quite stable (every 30 days never missed). I am now 25 and since November I have had my period 3 times: November 15th, January 31, and April 14th. When I did have my period I did not notice any changes in flow etc...
Since December I have also developed persistent severe acne on my chin which I have no history whatsoever of. I believe the two are related. I went to a clinical nurse for a gyn exam and said she couldn't figure it out. She ruled out Ovarian cyst based on my feeling no pain - although she was not able to physically check for ovarian cyst because I was "too tense" to check. So she prescribed Desogen which I have been taking since about June 17th. I don't know if it's a symptom of the birth control but now I often experience a sharp scratchy feeling in my lower right abdomen. I have a pretty strong guess that when I reach the end of my birth control for the month I will again have no period, but this is obviously just my guess. The desogen helped clear up my skin to moderate acne.
I have had no changes in diet, life situation, exercise (moderate), or stress.
Do you have any hypothesis of what my problem could be and if so is it serious enough for me to go in for another exam?
