Breastfeeding

I am 10 months pp i had my first cycle in may around 4 months pp. i didn’t have another until October and I’m a day late and not feeling great so i took a cheapie test which was sadly negative. I guess i was just wondering if i could’ve ovulated much later than i was supposed to (i do have PCOS too) or if I’m just going to skip a few months again. (Also not here for the “you need to wait” preaching 🤗)
