I dont know where to begin

...sometimes I think when you turn 30 you fall apart. This year, I found out that I have a low thyroid. After not having a regular cycle, further testing revealed that I also have PCOS. I wont have a following appointment with my Dr. until may, but she mailed a letter confirming PCOS today. Stated that my DHEA was 2221/ ng/dL Does anyone know what the normal range is?
Ive tried to read what I could, and will read more as I get some time. I just have so many questions.
Do I need an ultrasound? Will it help just to see how my ovaries look?
I do need to have a regular cycyle, so Im assuming I will be put on Birthcontrol? Is there any 1 type that stands out for treating PCOS?
I have noticed hair growth on my chin. Right now I have been plucking it? Would it be best to try and get my hormones under control first then try hair removal? Any medications out there to help slow/stop hair removal?
From what I understand, just becasue one may have a cycle it doesnt meant one is ovulating? My question is, though I dont want children right now, I do want them in the future. Is there any way I get get a normal ovulation again? Is there any medications out there that can help one achieve this?
Right now, I am overweight. I would say about 75lbs. So this is something I know I have to do on my part. Not going to be easy...but I know it might help as reguard with insulin resistance?
Sorry for so many questions. Its just that where I wont have an appointment until May with my Doc, I want to try and find out about some treatmetns/options from those that are experiencing this, so I can be better informed when I do see her.
Any help/comments will be greatly appreciated.
