What is this?!

I know it's tmi bit I've never had something like this before and I have no idea what to think of this. We had a complete CP on 6/10 and was given the okay to try soon as we were ready. Well today my period is due. This morning I thought I started but it was looked almost like white cream and when I just went to the bathroom this was what I got. Does anyone have an idea as to what this is or means?
