I started a new bc in January and instead of me waiting for my period, I skipped it and started a new pack. The first week I spotted ( I'm assuming from skipping my period) and then it stopped. I decided to wait for my withdrawal bleeding and last pill was on the 15th and my period started on the 19th and my 7th day was on the 22nd. I started my new pack of pills on the 23rd of Saturday and I'm on my 3rd pill from my new pack, but my period has not stopped. Im not having heavy periods, but when I wipe, I'm still getting sticky fresh looking blood. Why wont my bc stop my period?
