I've been on the pill for over 3 years and I've never had my period early with it. But today (3 days before I usually start my period) I had some brownish discharge which I didn't think much of, but I just went to the bathroom and looked at the liner I had and there was bright red blood on it. There isn't a large amount of blood but I know what my period blood looks like and it's not that bright of red. I'm not sure what it's from or if I should be worried. I know it's different and that makes me nervous. Here's a pic below. Has anyone had this before or have any thought on what I should do?
