I have been fingered, but never had sex. But one of my periods came a week early right after I had a ct scan, I'm wondering if that had anything to do with it. I've still been getting my periods, and they have been heavy and bright red. I have been getting headaches, UTIs, and constipated a lot lately, but IBS runs in my family so that could be that. My stomach is sort of hard right around my belly button, but I think it's poop. Have had nausea a lot, just a couple times. Been getting heartburn a lot too, and indegestion. I'm 14 if that helps
