Pee sensation? ?

Maria • 26, SoCal, 2 dogs, 1 cat, married & trying to have our first baby!
Just today I experienced the urge to go pee but when I tried only a few drops came out but my bladder still felt full. I'm 6 weeks 2 days...... any ideas? Maybe UTI?! and I'm not sure if this is related but my belly button area started hurting too (sore to touch).
