Slimy discharge RIGHT after?

Bonnie

I got my period on the 6th and it was red for 3 and a half days. No clots nothing bad at all. Since it’s now the 11th, for the rest of those days basically the blood will go away and I’ll get slimy clear discharge tinged pink or red. Only sometimes when I go to the bathroom it happens. It’ll be so slippery my hand slips when I wipe🤦🏽‍♀️ today it was slimy with some red/very light brown in it. I’m really confused because this doesn’t happen when I get periods. I’m ttc and it does not look like sperm? Is it sperm? I know I won’t be ovulating yet. I’m just confused cause it never happens. Before I got my period my body was being weird and my boobs felt like they were full of milk and about to spray everywhere. (They aren’t any bigger) and I was getting lightning pains in my vag. I took a test 2 days before my period and negative. Can someone help, what could the clear discharge be? Just sperm? I’ve only had sex twice
