Question ladies

A few minutes ago I when to use the bathroom. I felt like I was bleeding since I felt so wet/slimy down there. Well I did have CM (watery) on my panties, it was a slight pink color with a tiny red line. Also in the toilet water it had chunks of what I assume was CM which was a slightly pink color as well. It looks like semen like when you end up having sex in the bathroom and sit in the toilet right after he finishes lol and the semen is just in chunks in the water (if you can relate). Well the question is ... is this my period? I've never had this happen before.
