I'm having hypothyroid. I'm taking thyroid medicine from 3 years. I have irregular periods like after two months or three months. For inducing period doctors have given different medicines. I get chest pain for every small reason from many years. If I'm hungry, if I'm tensed, if I have to pee, for everything small reason I get chest pain. I have been to cardiologists few years back and they said ecg is normal. Since I have this issue please tell me a period inducing medicine without this side effect. Thanks and regards
