24 weeks and cramping?

Chava

So I'm about to be 24 weeks and the last few days I've started getting menstrual like cramping. I know it could be Braxton Hicks but I don't remember getting them this early. I thought I was well into my third trimester before I started feeling this cramping. Anyone else having this or know if it's normal. It literally kept me from falling asleep last night from it getting uncomfortable.
