I Have To Pee Every 30 Mins, And I Dont

i have to pee every 30 mins, and i dont urinate a lot. when i pee its clear, ive been drinking tons of water, but when i wipe it just started to be a pink. it doesnt hurt when i pee, but it does when i am finishing. is this a uti? i have been trying to conceive. could it be im pregnant? ive never had a uti before...
