Thank you for your query.
the condition sounds like symphysis pubis dysfunction.
this condition is very common and painful during pregnancy
Due to the effect of pregnancy hormones, the joints and muscles and ligaments of the pelvis relax and often cause pain.
You should try physiotherapy
Also, measure your calcium and vitamin D levels to check for deficiency.
Consult with your obstetrician so that any cause of uterine pain is not overlooked.
