Hey everyone, I am wondering if someone can help me. Well, my doctor prescripted me a birth control pill with the name of Althea due to my prolong menstruation. I know that it is a 21 cycle birth control and contraceptive pill, but I would like to know how effectively it can protect me from an unplanned pregnancy. My boyfriend is willing to ejaculate inside already long enough time so I was thinking that I can give him this opportunity while I am on the pill. I have heard that it is going to work after 7 days of taking the pills, but I am not sure and that's why I am wondering whether it is to be safe if he ejaculates inside. Is this true? I want to ask this question especially to those women who already gave a try to this birth control with name Althea. Some personal, non-commercial experience is going to be deeply appreciated.
