Is this labor pain?

Hey mommas! I’m 38w3d and I’ve been experiencing pain (in the areas encircled below). The one near my groin has been on and off since last week. usually happens after I lay down or sleep, and when I switch positions in bed. Makes it hard to move especially when I wake up in the morning. And is usually accompanied with back pain. The one near my belly button just started around 30mins-1 hour ago. It’s like similar to sore muscles. It’s been steady, doesn’t come and go. But has been getting less uncomfortable. Is it because I was sitting down for more than 2 hours earlier? I had an exam that’s why I wasn’t able to get up at all.

Or is this the start of labor pains? Anyone else experiencing the same?
