Hii, I am 25 years old. I usually have regular periods but since april (my night shift started) my periods are very irregular. I got my periods on 22nd aug after 3 months with heavy bleeding and clots. My doctor advised me to take regestrone and trapic. Also asked me to get hb and thyroid tested. The reports said t3 and t4 levels are normal but tsh level is 8. After 2 days of regestrone and trapic my periods stopped. But detected spotting after 3 days. What exactly I should do now? Will my periods get regular again?
