What Is It??

I’m 16 and lost my virginity 3 days ago. I’ve had sex twice In the past 3 days btw. Today I pulled down my pants to go to the washroom and I had creamy white discharge and idk y but it scared me. What could it be?? Is it from the sex or just my body? ( I’m supposed to get my period in 6 days btw) so u know I’m on BC and we used a condom plus he pulled out. Thoughts??
