What the hell is going on

Okay guys! So I have unexplained infertility & ever since having my son I’ve had a normal period for the first time in my life (but still don’t ovulate). Well this past month my period was 10 days late and I ovulate between the 15-17th day. I just had my period less than 2 weeks ago so I shouldn’t have my fertile window till this next weekend. Well if I got my period when I was supposed to, I would be ovulating right now. Since I don’t ovulate on my own, I don’t get fertile cervical mucous. Well now today I got this.... what the hell is going on?¿ if my period was on time, this would make sense to have this fertile mucous right now...but I shouldn’t have it for another week. If I’m actually ovulating I’m seriously going to cry!!! My mind is blown.
