Pain :/

Anyone else having a "sore" feeling in their vagina? It's like I've just had sex for the first time in long while and it hurts to walk or sit. It's not sooo painful that I feel like I should be alarmed and it comes in waves, but it's uncomfortable enough for me to wonder what the heck is going on. I looked it up and the Internet said it could be a bunch of things but isn't abnormal. I'm only 12w 3d. I guess I didn't expect there to be an issue down there so soon?
