I’ve had this too and midwife said it wasn’t a usual pregnant symptom. I think it’s because I’m generally less active and lay down more so my posture isn’t great 🤷🏻♀️
I would try getting a pregnancy belt, this really helps me otherwise i find I have excruciating back pain after i stand up for an extended period of time
i had this …. my midwife was said it isn’t typically a pregnancy thing . I ended up having a scan of my kidneys to make sure i didn’t have a kidney infection. Ended up just being pregnancy since it went away after birth 🤷🏼♀️ I think it was linked to my sciatica but never had a clear answer to what it was
Speak with your midwife they maybe able to help or maybe try a warm relaxing bath yoga I suffer with sciatica normally and my pregnancy has brought it intense time worse to the point I'm struggling to get around sleep everything and there is nothing I can do most days I could cry I have a toddler who I have to look after and I'm a full time student
