Can a hypertension thyriod make a person not be able to get a cycle to get pregnant?? I have had regular cycles for 2 years. At that same time i found out i have a overactive thyroid. In June i got a cycle. In July i didnt get one but i had spotting. Now this month nothing. I have had 2 home pt done. 1 er and 1 by my primary care doctor. All came back negative and all urine. I had a miscarriage in 2013. Please help me
