TTC but ovalting isn't right

I'm 33 i lost my virginity 4 day's ago to my husband that we have been together for 12 years, We are now wanting to try to convince our baby! But I've tried every app to help with ovalting, this afternoon i went pee and wiped and had a little bit of bright blood on the tissue but it went away fast. Glow is never correct with my periods or anything due to the fact i have VERY irregular periods and mine usually last 2 week's (Doctors Know) so at the moment im not sure where i stand with ovalting but me and hubby haven't used protection in the 4 days we've had sex we try to have sex everyday to make it may be happen i feel like because of my PSCO it'll be hard to even convince. How do you honestly know when you are ovalting? It's weird because even with my period i never get cramps never in my life nor do I ever get moody or anything i never even know wnen my period is coming because my body never gives me a signal.
