Hmmm tmi but curious lol

So this morning my fiancé and I were messing around and when we switched positions there was heavy creamy 'discharge' whatever you wanna call it. I have been on nuva ring and yesterday was the day I'm suppose to take it out to start my period for this month. So I'm just wondering if before you start your period do you have milky discharge like that ?? Cause I never have before..so that's kind of why I'm asking lol. Thanks.
