First PP period - expected or unexpected?

Hello, everyone. I had my first baby 6.5 months ago, and am breastfeeding around the clock, so I haven't had a period in a while.

Lately, I've started feeling somewhat interested in sex for the first time since sending a person through my vagina, and then earlier this week, I got typical "your period is coming" signs - moody, craving junk food, and then I had a migraine from Tuesday night to Wednesday night. So I was SURE that I would start bleeding yesterday, but nothing. Instead, I went back to feeling pretty much normal.

Has anything like this happened to you? When you got your first period after baby, did you get a decent warning, false alarms, or did it come out of nowhere? Should I be tracking in the app, or will I confuse it? Thanks!
