Mmm I Just Lost My Virginity Recently And Been Having

Mmm i just lost my virginity recently and been having sex for two weeks.
Everytime before and after sex i would try to pee and wash myself.
Christmas day after i had sex,i went to wash up and pee but it hurt.
Its been days so i assumed its UTI,and took some UTI relieve pills for a day, my pee was orange color with this strong scent.
Now the color is normal, although theres still some strong scent. And after i pee my vagina itches, and i think its smells like seaweed.
Its been like this since 24 dec. pls advice
