Hi i am 37, and i am going to have my 4th baby after 7 years. I have three kids 2 boys (9 and 10 years) and a girl 7 years. I didnt had any complication on my other pregnancies. After I got pregnant only they detected that I got hypo-thyroid. Doctor gave me cox-thyrox tables 50 micrograms. I am taking this for about 4 days now. My problem is I feel very difficult to breath, Always tiard, when it comes to evening I cant wait at all,, its like someone is squeezing my neck. I am very depressed with this disease. Please advice me to get rid of the feelings.
