Cramping while breastfeeding 4 months later?

🤱🏻mon • Baby Finn Born 10/6/17💙

I exclusively breastfeed my son.. I know in the beginning I had contractions to shrink my uterus when I’d feed him, which they stopped after a week or so... here we are 4 months later & I started getting slight cramping every time I breastfeed again. They feel like light period cramps? Has anyone every had this before?

-I haven’t gotten my period back yet (knock on wood)
