Hello, I would be happy to help you with your question.
If you are going to take the pill for birth control, you MUST take it at the same time every day. The way you are taking it is doing nothing but making your cycle more irregular and producing hormone related side effects - and all the while not really providing adequate birth control.
Going forward, you must use condoms and come up with a better way to take the pill, or consider some other form of contraception
I hope that this helps. Please contact me through the PREMIUM SERVICE if you would like more detail or a more timely response - Dr. Timothy Raichle
