Is this baby coming????

Did your baby come like extremely early and if so what were your signs? I’m just shy of 34 weeks so I’m really really hoping this baby stays put for at least 3 more weeks 😅 but I did a long steep walk yesterday, I wouldn’t normally do it but I was running late for school pick up… All day I’ve struggled to walk, it generally feels like there is a watermelon dangling between my legs.. last night I’ve thrown up, have a huge migraine and babies moving in my vagina, like I can feel her wriggling actually inside the vagina 😅😅 sorry… and I’m also getting sharp pains with it plus she’s moving like crazy & loads of braxton hicks… Should I be concerned or is this all pretty usual for this point in pregnancy? (I didn’t experience this with my first two)
