Torn muscle?

Wondering if I maybe tore a muscle or something.

I had my baby shower yesterday, lots of bending and standing.

I woke up today (well Sunday) multiple times during the night because my lower left side of my belly was so sore. Sore to turn in bed, get up, walk, sneeze, cough, laugh. It’s so weird and not Severe pain but very annoying and achey and it gets worse when I walk and stuff.. I see my obgyn tomorrow but damn I’m wondering what the hell I did?! This is Not round ligament pain as I know what that feels like and I’ve had this pain literally all day!

Anyone have this? Any advice or know what I did??
