Stomach Flu

BK

So my husband had the stomach flu about a week ago. I thought I had beat it, but ever since 4 am this morning I had stomach pains and then since breakfast this morning I haven’t been able to keep anything down, even water. I’ve slept for a while. I’m 29+5 and baby has been active today despite this sickness, but does anyone have any ideas on remedies to help. I don’t want to end up dehydrated and have to make a trip to the ER or anything.
