Any idea as to what this may be?

My SO and I had sex last night. Right after that I got these sharp stabbing pains in my lower abdomen. I figured it was just some pain from having sex..It took me forever to fall asleep and I even woke up to the same pain. It literally feels like someone has a hold of my insides and is ripping them apart. I want to cry it hurts so bad. I couldn’t sleep on my stomach because of how bad the pressure hurt. Any kind of pushing on the stomach and I’m in extreme pain.
