Worst third trimester symptom

Jessica
I flip flop on what's the worst, but today it's definitely being unable to pee when I know my bladder is full. I'm pretty sure my baby is blocking my flow and it hurts so bad. This happened to me earlier on and I thought it was a UTI. I'm always able to pee eventually but not at first, it's so frustrating and painful. 
I say this having experienced sciatica, SPD, harsh Braxton hicks, etc. This will easily be my favorite thing to leave behind once the baby comes.
