My 23 year old daughter just went through very similar things while on the pill. Finally after testing everything under the sun, thyroid, adrenal glands, you name it, they tested for it!!! What they found was her testostrone was elevated. Her docotor said likely from taking the pill, and that she could expect it to regulate it's self now that she has opted to go off the pill they are tryinging to start their family.
Interesting to read your post. I hope you get things all figured out!!!
Good Luck to you!!!
