Normal i get this all the time! Especially when i'm laying down for a long time
I'm 14 weeks and the same thing is happening to me. It's called round ligament pain. Basically our uterus is growing and the supporting muscles are stretching. We're bound to be sore! I had it earlier today and had to talk myself out of a panic attack by telling myself it was a sign all was going right, not wrong haha.
Sounds pretty normal to me.
