Cramping only during the night

Hey I’m two days till my due date, miserable AF 😂 for the past week I’ve been getting intense cramping that doesn’t develop into anything and the day goes on. Last night however I woke up at 3am with cramping again, but it went round to my back and was all in my side and made me feel sick. I started timing it but again, vanished and it’s like it never happened this morning.

I’ve not had any of this during my pregnancy, is it just my body getting ready? Honestly I’m over these pains so much they’re making life miserable
