A lil curious what's going on?

so i looked at my calendar and me and the bf had sex 3 times in my ovulating week. i'm not worried if i'm pregnant or not the not my question. What exactly happens when your done ovulating or during implantation? i've been having off and on lil baby cramps for the last day or two...and today had some type of secretion in my panties, it was kind of clear with a lil whitish hint but not really (if that makes sense.) i just need to know what going on, and if i am pregnant if that's supposed to happen when you conceive...if its left over from intercourse 2 days ago. shine some light please and thank you.
