Is this normal??

Lately its been really difficult for me to pee sitting down. I’ll end up sitting on the toilet and peeing 4/5 times in a 30 min period because I cant get it all out sitting down it seems. I’ll literally have to stand up in the shower to pee or run a bath and sit in the water and get all the pee out and then wash myself off afterwards because peeing in the toilet is not emptying my bladder out. Is this normal? I thought I may have a yeast infection I got medicine from my doctor but its still doing this..
