i find i go to ladies room often as well and i am defintly not preganant. I f you are drinking a lot of fluids on an empty stomach this may be doing it as well.. I find if i drink coffee, tea or water i will go more often. If you are really concerned get your docter to check for diabities. not sure if this runs in your family or not. hope this helps
Generally having to pee a lot comes when the uterus begins to push on the bladder. By then you would already know you were pregnant from many other signs including an increasing stomach. Take a home pregnancy test if you are in the early stages of wondering, symptoms just don't reveal anything.
