Weird Cramps?

Holly • Wife 💍 Mom to two beautiful little girls 👧🏼🎀👧🏼🎀 Baby #3 due September 2023 🤍
I've felt kind of crampy off and on all day. I was sitting at my desk at work and I started cramping in the area near my ovaries, on both sides. The pain shot around to my back. The pain was so bad that I was bent over crying. The pain eventually eased up. I'm going to send my doctor an email to see if I should come in.
 (I have skipped two periods and all the pregnancy tests are negative). I go back August 3rd to run tests if I have not started my period or got a positive pregnancy test
Has this happened to anyone?
