Has anyone had their period start back up after is stopped? I finished my last birth control pill Saturday the 6th of Feb. I started my period that Wednesday like normal. Then it ended late Sunday the 14th (which I should have started taking a new pack but I didn't have a new pack yet). Monday my period was completely gone but Tuesday morning (today 2/16) I have horrible cramps, diarrhea, and it came came back heavier than it was before. Has that ever happened to anyone?? This is the first time I had more than a week between packs.
