10 months postpartum and cramping

So for the second time since having my baby, first episode happening at 8 months PP and now for the second at 10 months, I have been having period/pms like cramping.

At 8 months PP i cramped pretty hard for about 5-6 days, having almost all the symptoms I would usually have during pms. I waited for my period to show but it never did.

Now at 10 months PP again I’ve been cramping for 4 days to the point I needed to use a warm pack on my belly and turmeric tea to alleviate the pain. Also having the typical pms signs except for tender breasts.

I breastfeed quite much and I know that periods can delay for up to a year due to this. But is it normal to cramp like this for so many days but not have a period show up?

Has anyone ever experienced this? When did your period eventually show up?

Thankful for answers!
