Sharp ripping/tearing-like pain in lower abdomen. (???)

Hi ladies! I don't know if this is TTC or pregnancy related at all since AF isn't due for another week, but you all have been so helpful to me in the past, I'm hoping someone has experienced this before and could help shed some light on the situation. For the last 3 days I've been getting this sharp, almost ripping or tearing-like sensation in my lower abdomen, just below my pelvic bone. It comes on fast and sudden (takes my breath away), and only happens when I'm laying in bed and go to twist, turn or roll over. I've never experienced this before (that I've noticed), and am wondering what could be causing it? Has anyone ever experienced anything similar, and if so, what was the cause if these pains? Like I said, it isn't constant, just happens when I change positions too quickly while laying down, but even as I type this, the area where it happened this morning still feels mildly sore. If anyone could offer any insight, it'd be so appreciated! Thanks for reading!:-)
