It is important to take your pill every day at the same time each day. Any interruption can cause you to become pregnant. If you forget your pill, take it as soon as you remember and double up that day to get caught up. Use a condom until you start your next pill packet.
Any pill for birth control works the same way. If you don't take it everyday at the same time, there is a chance you can get pregnant. You must be on solid birthcontrol everyday for a month before having sex in order to not get pregnant.
From a man point of view, I have seen this question online too many to count. Its really a simple question to answer. All you have to do was to read the instructions that were written inside the birth control packet. I am quite sure that your GYN had brief you with precautions when you missed a 'pill'..by having sexual intercourse...
Sounds like if you are trying to become pregnant..You know the answer to your question.
