I Finished My Periods On The 9th Or 10th. On

I finished my periods on the 9th or 10th. on the 15th i had sex and my boyfriend pulled out to cum, he cummed then wiped it with clothes and then i suck his dick and he wiped it again and we continued as the dick was dry. Can i get pregnant?
i'm scared
and also lately my urine is water color and sometimes dark yellow and i get white and water color discharge that is slimy and weird stomach feeling, is that a problem or is it normal?
