A little tmi question..

So I’m 25 weeks pregnant and every time i have to go #2, it’s diarrhea. I’ve had it like this for about a week or so now. It’s not like an all day thing, just when i have to go #2 like in the mornings...has anyone else had this or heard of this??..i heard constipation was common, but not this. I did call my doctor and she said it doesn’t sound too serious since I’m not bleeding or dehydrated.
