Since I've started using the ortho pill for birth control I've had two normal periods. The third period, I started a new pack instead of taking placebos and I didn't have my period. I did that for the next period too. Then, I accidentally took my pill a couple hours passed usual time two days in a row and I started spotting around when I was supposed to get my period. And then it turned into a light period and now I've had my period for 11 days very lightly. I don't know what to do, advice?
