Thanks for posting your query.
It seems you are having a gut infection that has resulted in watery diarrhea
The biggest risk with this type of illness is dehydration
and resultant hypotension
and threat to pregnancy
So make sure that you replace slightly more liquids by oral intake than what you are losing through liquid stools.
And also take good amount of nutrition.
You are pregnant so antibiotics are not advisable.
