On Amethia Lo, took 1st pill Thursday by mistake due to PMS symptoms--didnt start active pills again until Monday, still bleeding, how do I stop it?

Double up for 5 days. I am assuming that you have been taking Amethia Lo for sometime already. If the bleeding is heavy or bothersome to you, then you can take 1 tablet twice a day for 5 days and then go back to 1 tablet daily. It may correct the problem sometimes. However, if you have any concern about pregnancy, please do a pregnancy test. Feel better soon.
