What does this discharge mean?!? Tmi PICTURE FAR DOWN PLEASE HELP😫

So me and my boyfriend had sex and he cummed in me on the 30th August two days before my period came , it wasn't my usual period but not too far from it(I'm just very observant with things going on in my body) so anyway I didn't think I would be pregnant as I wasn't ovulating but I did have cervical mucus then. But anyway so my period stopped on the 5th Septemebr(my periods last 6 six days and cycle length 36) it was really brown and then light and spotted and then sometimes normal so now I've got this discharge but I shouldn't be ovulating until cycle day 21?!?! Could this be like pregnancy cervical mucus. I only get discharge during fertile Windows...
