Any moms with regular periods after birth experienced a delayed period at 10 months PP?

Question

So I have a theory that at the ten month mark, it’s common for postpartum mums to have a delayed period with negative pregnancy tests. Please help debunk my theory. 
If you voted Regular, late at month X, what month were you late? 
Late means anything from 1 day to weeks.

Answer

Following. I’m having the same issue. I’m almost 6 months pp and all my periods have been regular so far until today. I was supposed to start my period yesterday but it hasnt came yet. I don’t have any symptoms of pregnancy so I really don’t think I could be pregnant.

Answer

Before having my son I was irregular. After my son I was pretty regular...until about 13 months PP. Then it disappeared for 2 months. Then I got my period in December. I got pregnant again the following month. I'm on birth control now so my period is completely regular.
