Ok, we are trying for a baby and I am scheduled to start my period Thursday Nov. 3. I have been having this urge to pee CONSTANTLY for a few days, with horrible back pain longer than the urge to pee. The urge to pee is so constant that it wakes me up. It's horrible! Went to the OB checked my urine and found no UTI or any other probs. She also told me that my symptoms may not be related to pregnancy. Not sure what to think....Can't take a test till Friday. Any advice or thoughts?
