32+5 so uncomfortable

Any mummies experiencing the same? Is it normal? My lower back starting to hurt constantly. My belly having pains and I can't lie on my back. I have to lie only on my sides to get some relief. When I sit I feel pelvic pain. Baby is growing normally and average size at this point but ultrasound shows baby head lying really low at my cervix. I can no longer walk without feeling tired/pain/discomfort. Will prenatal massage help or do I have to endure this every single day until I deliver? I am also diagnosed with GD and low iron. Both are managed with diet control and supplement. Btw I dunno if the belly pain is BH because all along my BH never was painful. Now I feel sharp poking pain around my tummy or like nerve pain sort of. My legs are getting weak due to the increasing cramps lately. Any suggestions will greatly help.
