I had symptoms of pregnancy about 2 weeks ago. Still not sure if pregnant.
Then 2 days ago I started having really weird bathroom trips. First I had to go pee every 30 minutes. Then, every time I urinated I felt like my pee was cut off and a sharp pain occurred at the urethra. When I would stand up I felt like I still had to go pee but couldn't. It doesn't hurt otherwise, but I always have to go pee. Anyone know why?

You need to see a Physician - it could be anything.

Sounts more like a bladder infection or another type of Urinary tract infection.
