More symptoms after miscarriage ?

I had a miscarriage about 6 months ago. But I’ve recently realized before I was even pregnant when my period would come I didn’t have pre-period symptoms like: cramps, tender breast.

But now after the miscarriage I can feel it a lot lot! Like my boobs are so tender a few days to week before my period. Can anyone explain this? And when I ovulate sometimes I cramp a little.
