Pain in groin??

Hello! So my Husband and I just found out we are expecting our 3rd baby (yay ❤️) I should be around 5 weeks pregnant. Last night though I started have some really intense deep pain. On the right side where my groin meets my hip, it only hurts when I move though. I feel perfectly fine sitting down, it feels like maybe a deep pulled muscle? I’m just wondering if this is something I should be concerned about, and if it has anything to do with my new baby. Any advice would be greatly appreciated!
