30 weeks pregnant and my private area smells really horrible and fishy.....

sorry it sounds like a silly post but I had protein in my urine and had it sent off and i had to be put on antibiotics for a week as I had a bacterial infection or something I was last seen at 20 weeks pregnant and they didn't want me to be seen again until 28 weeks but my midwife got fired so now have a new one but haven't been seen yet I'm 30 weeks pregnant and as I've just moved I've had to change doctors so have to book an appointment tomorrow I'm just worried as I've had this smell for a while now so not sure if it's a bacterial infection again??? or what could it be?? my vagina literally smells of fish it's disgusting and makes my underwear smell

this is my second pregnancy and I came early with my first born at 35 weeks 4 days
