Occasional hormonal cries yet?

I’m fairly certain I don’t have ppd but every 3-4 days I’ll have a total cry about nothing really. It can be simply that I’m happy my baby is healthy, or his toenails started growing in (was premature and had no toenails) or along the lines of being overstimulated, he’s squirming too much and I can’t handle being touched/scratched anymore.

Anyone still dealing with these swings? Is it normal? I had ppd by now after my first two, this feels more like baby blues but at 12 weeks pp, shouldn’t that be gone?
