hi doctor, I have irregular periods. My doctor prescribed me Meprate 10 mg for 5 days, 2 tablets a day. she told me to take the tablets and that i should get my periods after 2-3 days. It has been almost 5 days now since i finished taking the tablets but i did not get my periods. I also tested pregnancy using PTK 2 days back but it was negative. If anyone has some experience with this medicine, please write.
