My period always comes when I'm in the middle of my birthcontrol pack.. Usually around the 12th-14th day.. Whats with that?? Does this happen to many people.
I get some spotting around that time. But not always. I also only spot a little near the end of the pack.
This happens to me on occasion, too. It's is not normal, however, and not good. I went to my doctor and found out that it can be a sign of endomitriosis. I do have endo, but it doesn't mean that anyone who bleeds then has it. But, it can be an early warning sign, as well as fierce cramps and serious migraines. Your best bet is to see a doctor about it. At the very least, you'll get piece of mind.
