16 months postpartum.

I'm currently 2 days late. With it being my second period since having a baby. Had my first period at 15 months postpartum. I'm hoping I'm late for a good reason and not my body still trying trying to adjust to having periods again. Anyone else every deal with this? With my first my period showed up at 8 months pp and was like clock work til I got pregnant at 11 months pp. I feel like I don't know my body anymore 😳😬 help a momma out! Am I crazy to think I could be pregnant?
