Please help me !

In april 2006, my daughter was in a car accident and needed xrays when they did them they found a mass on her ovary which was a dermoid and she had it removed in november 2006 along with one of her ovaries(which we were told the dermoid took over the whole ovary and it could not be saved). My daughter who is going to be 20 in 9 days didnt get a period until she was 15 ever now after surgery and being put on the nuva ring to regulate her period, shell only get a period for 1 day. she also says that if she wears a pad the blood is only on one side of the pad. she is very frustrated not getting a period becuase she feels it makes her less feminine. she also get some boils on the side of her face(she says they are not pimples) and has some strays hairs that pop up on her face which she plucks quickly. her doctor thought she had pcos but did bloodwork and now said she doesnot. i want a second opinion. what kind of doctor do i look for? a specialist? if so, in what area? or a regular board certified obgyn....please help me and shed some light on this situation...

thank you so very much
