Got my BFP but no idea when I ovulated

I’m curious if anyone has been in my situation and could share their experience. So I just got a BFP and it was my second postpartum cycle (baby is now 15 months old- still breastfeeding a decent amount). The thing is, I never really got any signs of ovulation so I really thought I wasn’t ovulating. I usually have around 30 day cycles and had ZERO LH surge mid cycle so I gave up on testing and just forgot about it. My expected period day came,(11/1) negative pregnancy test. Tested again 11/4 faint positive! Subsequent tests have gotten darker and I feel have good progression. My cycle had started 10/2 and I believe I could have ovulated anywhere from 10/20-10/26. Has any other breastfeeding mama had a successful pregnancy with unknown/late ovulation? Beside some mild cramping I don’t really seem to have symptoms like I did with my daughter. I hope this little baby will stick! Please let me know what you think or if you’ve been in a similar situation!
