Hi, just want to know on how possible will i get pregnant during on my fertility days, during sex im on a cowgirl position before he reached his orgasm he withdraw some and put it back in, after that i took a quick bath and pee, will i get pregnat?

Sure, it's possible: Fertile couples having sex in their "fertile window" have the possibility of getting pregnant. If they are young, healthy, and fertile, they often get pregnant within 4-5 months of steady sex. One can look at it as a 20-25% chance of getting pregnant each month... but what does that mean? Mathematical numbers have little meaning to an individual because she may be the lucky one or the unlucky one.
