I had sex multiples times last week (about a week and a half ago) and for a few days after my vagina felt... Odd. It felt like it had been torn a bit but is better now even though every so often it still feels that way. I'm now having what looks like light spotting and it kind of burns to pee. My SO and I were both virgins when we got together and have only had sex with one another. I woke up today with a migraine that's coming and going along with feeling pretty sick to my stomach. Any ideas what might be going on?
