Frustrated!

This is just a vent post, I have never had "normal" periods every month, but I could at least count on them showing up 4x per year on the first full moon of the season. Since I had my first baby 16 months ago my periods have been all over. I'm 13 days "late" not pregnant and I'm still testing positive for ovulating for 2 weeks.... tracking cycles is hard. We're not actively trying to get pregnant, but we aren't preventing either. Idk, I'm just ranting lol I feel like my friends (none have kids) and spouse just don't understand lol
