Slipped and fell!

I was walking outside in my neighborhood with my husband and dogs and hit a patch of mud I didn’t see. Slipped backwards and fell on my butt. I somewhat caught myself with one wrist, and the fall happened relatively slowly I guess, but I am so freaked out it happened.

Called the OB and they told me to start with kick counts so I’m doing that now. Baby girl is definitely moving. Feeling a bit crampy and sore where I would normally get round ligament pain, but nothing severe. No signs of labor. But I’m so far along, 37 weeks, and I’m just so upset this happened.

Has anyone else fallen in late pregnancy? What happened?
