Cycle screwed up this long after birth??

Shari

Before I gave birth I was VERY regular....I got my first post partum period @ 3 months. They've been RIDICULOUS every since. My cycle ranges from 28-32 days, my husband and I have been trying to get pregnant again but I don’t know when I ovulate and ovulation test is always wrong on me

My son is 9 months old...anyone else having a messed up cycle this long after birth?? Thanks! Just curious.
