FTM/ strong vomiting

Jennifer • 23yrs, happily married and expecting our first Lo Austin Xander in November.

I'm 18+1 today, my morning sickness has definitely eased up as long as i eat when i wake up.

Today I've felt fine, no nausea. At about 10:30pm after brushing my teeth i vomited everything I've ate today, like seriously so much i had to flush the toilet 3 times to continue w/o overflow or splash ups. It was something i havnt experienced. Almost like my body hadn't digested any meals since the AM.

Now i have a very sore tummy and i guess my question/s would be..

Could this cause high ketones?

Should i try to eat something since I've lost it all, or wait till the morning?
