Body emptying

I think my body is getting ready.. last night I woke at 3am with belly ache. Ended up coming out both ends over a few hours 🤢. Had crazy pain all over my stomach which I think was painful BH?! I've had non painful BH over the last week. Managed to get an hours sleep & now I just feel knackered & nauseous with a few aches and pains. *second pregnancy so I sort of know what I'm looking out for* just never had this with my first!* have any other mummas had this?!*
