Hii, I got my periods almost after 2 months after taking regestrone medicine. After that the nurse said to take ovral l medicine to regulate the periods from the first day when the menstruation starts. I did the same for three days but I somehow missed one dose so I asked her what to do now. She said that you have to take the ovral l medicine after the period cycle end. So will the 3 doses of ovral l will have side effect? Should I take the medicine after the periods end? If yes what if I missed a dose somehow? Please suggest me.
