With morning sickness, yes that can be normal. But your ob can also prescribe something to help with the vomiting
It's normal.
Some mommys lose weight at the beginning bc of the morning sickness.
I lost 11lbs during my 1st trimester.
Try eating freeze pops.
The ones that are liquid and you have to freeze, apple sauce cups and a few crackers.
Even if you only have one freeze pop, a couple spoons of apple sauce, and 2 crackers every 10-20 mins, it does help.
My doctor did prescribe zofran for the vomitting but its better not to take them .
Atleast not all the time .
It's better to try to deal with it on your own and only take the meds when you really need it.
