Snot clots in the shower

So I'm on the third day of my period(came off bc pills 3 weeks ago and this is my second period since then) and today when I showered I noticed what i know to be a small clot run down the drain then a while afterwards I wiped off of me what looked to be one big and one small snot clot of blood and kinda clear stuff. 
Anyone know what this is?. It was dark dark red i though it was brown before.
