omg I'm seriously over this!

Seriously, after almost a week of a horrible migraine with only small meals and hydration, I'm thinking of going to the dr tomorrow, I can BARLEY pee, I feel my urethra is moving and I feel like I need to pee but only a little comes out💧- no it doesnt hurt yet🔥..but my urine is cloudy, I always clean myself properly after using the bathroom and shower after sex. I've always gotten UTIs and I dont know why!!! I'm 12 weeks pregnant. What antibiotics do they prescribe to pregant women???
