HELP

so all day today I feel like I need to puke (body wise)

but it's like it's not fully forming so it's not being more than just that body feeling ...

what could this mean ?

I am not dehydrated

I have had multiple shots to stop contractions

and I've had a 2 part steroid to speed up baby's lungs due to daily horrible contractions.
