Thread: Underactive thyroid?

I have been having weird symptoms lately. I would say this has been going on for over a year. It started when I noticed my hair was thinning. I've always had thick hair. Some of my other symptoms include:

*Dry patches on my stomach. Very dry skin patches, they are huge and red.
*Dry skin all together
*Thinning hair.
*Very fatigued. I feel drugged every morning, and I'm not taking anything before bed (like sleeping pills).
*Weight gain. I've probably gained about 20 pounds in the last year, and nothing has changed. My eating habits have actually gotten better.
*Finally, my menstrual cycle has been VERY off. I have never in my life had such problems. I've always had a heavy cycle, with painful cramps for the first day or two, but this is not right. Last fall, I went 3 months without a period. I wasn't pregnant, I took tests constantly. It did come eventually. I had a few normal periods, then it's back to being off. I was almost 50 days late on my last period. I'm on my period now, and it's actually 6 or 7 days early.

I am trying to get into a doctor, but it's hard because I don't have medical insurance right now. If anyone has any advice I'd greatly appreciate it. Does it sound like an underactive thyroid? My mom and husband think so.
