back to groin pain?

Britani

last I'll say two weeks, I'll get HORRIBLE back pain when I lay on my back. I don't sleep on my back but if I'm in the yard and lay flat for a second to loosen up, I'll sit up and the pain is aweful. tonight I was laying in bed, laid on my back for about 5 mins. sat up, back pain worse than before, like effected my walking it hurt so bad, and about 5 mins or less later it moved to my groin. baby's moving, no bleeding or anything. second pregnancy and ik DR said braxton hicks can start now but I never had them with my first or any issue literally at all. so its basically all brand new here lol! I'm going to call my DR tmrw and ask but I work 3rd and ik its gunna drive me nuts all night googling for answers lmao. TIA❣

I'm 26+2 weeks.
