Left Side Hip/Back Pain

Ashton

5 weeks exactly today with my 3rd baby. I’ve had 2 miscarriages in the past so I am paranoid. (Literally having nightmares) I have been having persistent aching pain in my left hip/lower left side of my back. Is this something I should be concerned with? Does anyone know? It’s not anything I ever remember experiencing before but it has been about 7 years since I’ve experienced early pregnancy.
