Late again 🙄

So anyone here breastfeeding? Did breastfeeding ever cause any problems with your periods once they came back? I’ve been regular since they’ve returned except this month and the second month after they returned. Both this time and last time I’m getting/had faint positives but nothing ever went past a faint line. This time I’m wayyyy later than I was last time before I started bleeding, on day 13 of no period. I’ve had questionable faint positives but nothing is getting darker so I’m pretty sure it’s not another pregnancy. Does anyone know what it could be? Or maybe what I could do to get my period to come back so we can start trying again?

I’m cramping like a period is on the way, my breast don’t exactly hurt like they did with my boys but I feel extra engorged (which I haven’t been engorged since my kiddo was a tiny baby), I’m emotional, and having insomnia at nights. All of which (besides the engorgement) is signs of my period, too.
