 [ Symptoms ] i am 35 weeks pregnant my urine has no colour with back ache please help [ Disease ] hi the intense back pain and pelvic pressure you are experiencing is due to the increase in the size of the baby now as it has almost attained its full growth this causes pressure and stretching of the sacroiliac joints causing severe pain u can apply local creams hot fomentation avoid taking any tablets consult a gynecologist if the pain is severe the urine colour u mentioned may be due to slight vaginal discharge that gets mixed with urine nothing to worry about until you can feel the baby movements thanks
