Should I be concerned??

Emily
I'm currently 19 weeks, and every time I go pee, after I have peed I get pressure on my bladder... Not a cramp really, but its uncomfortable. It lasts maybe a couple mins at the most and its only after I have peed. I get period like cramps every once in awhile but I have mentioned that to the doctor and she isn't concerned. Just curious if anyone else has experienced this? Thank you!
