Postpartum cramping?

So I’m 21 weeks with my second and my sister (who’s had three kids) told me that after the first one when you have more you get really bad almost labor like cramping for days after giving birth. I never heard of that before is that actually a thing? I didn’t have any cramping at all after my son but she said it doesn’t start till after the second one and gets worse with each kid you have. Is this actually a thing?
