I am an 18 year old young woman who has been very healthy my whole life. Starting in February of 2008, my periods went from being every 28 days to every 21. They were also EXTREMELY painful, heavy, and draining to me. I would get so sick that I wouldn't be able to lift my head off my pillow. I have also gained 12 pounds in the last 6 months. After going to see my family doctor, he put me on Yaz. Yaz took away off of my symptoms from my period and I was beginning to think it was a magical pill until the third month. During the third month I was taking Yaz, I became very emotional and could cry at the drop of a hat, crying for over 3 hours at a time. I was utterly irritable and would blow up and yell at my family for the littlest things. I also became extremely depressed and tired all day long. After returning to my family doctor, he switched my birth control to Femcon. I have been on this pill for one month and are seeing little improvement. I take my pill religiously at 5pm everyday. Around 2pm I can tell that the hormones are wearing off and become irritable once again. A half an hour after taking my pill, all of my symptoms are gone again. I am afraid to take the placebos because I risk becoming extremely irritable and have crying spells for a week straight. I have recently gone to the gynecologist for the first time. My blood was drawn and all of my tests came back in the normal range. After doing some research on my own, I have found that I have 90% of the symptoms of hypothyroidism. But since my blood tests came back normal, my doctor doesn't think there is anything wrong with me. I don't know where else to turn, I know there is something wrong with my body and everything just feels off. I am also a vegetarian but not sure if the two are related. I constantly have to watch the clock and avoid going to public places a few hours before I'm due for my birth control pill in fear that I will not be able to control myself and cause a scene when my irritability comes on. I am also in fear that by stopping birth control, all of my previous symptoms will return with vengeance. Living day to day is very uncomfortable to me since I don't have a diagnosis. I have heard that a blood test for hypothyroidism can be inaccurate. Is this true and does it sound like i have have a hypothyroid?
