I’ve been on birth control for the past 4 years. I’ve tried skipping my period twice now and without fail, I eventually get it when I’m not supposed to. The first time I skipped two months and then on the third month, I got my period halfway through the pack (week two into the pack.) I continued the pack, got my period again (when I was supposed to), and then started a new pack. Since that happened, I went back to taking the packs normally (getting my period at the end of each month.) Then two months ago, I decided to skip my period again. I skipped it for two months and then in the middle of month three, I got my period. The first time, I didn’t get any signs. It just came. It was light and the blood was brown. This time, I got slight cramps and again, it’s light and the blood is brown. What is going on? Why am I getting a period when I shouldn’t?
