I took Prometrium to start my period. My doctor said to take two each night for seven days. I am supposed to call him the day I start my period. I took the last two pills Wednesday. Can you tell me how long it usually takes for your period to start?

It usually takes about 3-5 days after the last pill. Give it a couple more days and it should arrive, but it can take up to 14 days.
