So my fiance and I had sex twice during ovulation week but he pulled put

1 of those times being pretty close. 1 day after it happened, I noticed I got a gush of cm and didn't think about it

When I checked my panties, and there was a white mark on there. I know it could be cm but do you think he could came in me while pulling out?

Btw we both wouldn't mind having another child; we already have 1.
