Lexiee, I am 11 weeks pregnant and about 2 months before I got pregnant, I was diagnosed with hypothyroidism. I had terrible periods that would last three weeks sometimes, but they put me on birth control when I was 17 and that took care of it. I had really bad hypoglycemia, severe dry skin, cramps, I was tired, and I had ocd (obsessive compulsive disorder) I would have to contract muscles in my body and if I didn't do it, I felt like I was going crazy. I mean the list goes on and on. When I was diagnosed, my practitioner prescribed me armour thyroid. It is a natural thyroid hormone. I felt a lot better and then I found out I was pregnant. After my 6th week I started getting signs of hypothroid again and they tested me and I am very very low. Pregnancy can really cause problems with your thyroid and it is a very serious deal. It causes miscarriages, stillbirth, low birth weight, and low iq. You need to go to a specialist and take your medicine. You will feel a lot better. You will never know you could feel so good. There is lots of information about it on the internet, and you should read it.
Oh, and I have always been very thin, and still am and I have had hypothyroidism they say for a long time. I have had almost every symptom, but the over weight thing.
