7 months pp and no period

My daughter just turned 7 months old and I still haven't had a period. I've been supplementing with formula for several months and she has been eating solids for almost 2 months. So basically she's eating solids 3 times a day, having 2-3 bottles of formula and only comfort nursing for a few minutes a couple times a day and once during the night.

Has anyone had a similar experience? When did you finally get your period?

I had spotting after intercourse today, light cramping for a couple days but that's gone now.

The past couple days, I've had some dizzy spells, I'm exhausted and my breasts hurt when I nurse. So of course my brain is jumping to pregnancy lol but I know thats unlikely.
