Diarrhea- HELP

Has anyone else had pretty severe diarrhea that

usually doesn't get it very often? It's very rare that |

will have an upset stomach from what I eat but for

the past 3 days I've been in and out of the bathroom

constantly. I'm almost 18 weeks pregnant and I

didn't have this at all with my first pregnancy. In

fact, my first pregnancy I noticed I was constipated

quite often.

It's Thursday night (Friday morning technically since

it's 1 am) and I'm still experiencing diarrhea that I've

had since Tuesday. I was very constipated to the

point where my stomach was in knots so I drank a

full glass of milk because usually milk helps get

everything moving pretty well for me. But since

about an hour or so after I drank the glass of milk

until now, I've been running to the bathroom all

throughout the day, and almost pooped myself at

one point. I'm 21 years old so I feel like I'm young

enough to not be dealing with stuff like this, days

after I drank just one glass of milk. Does anyone

have any tips on how to get my stomach back to

normal? At this point I'd rather be constipated again

and just deal with the stomach pains from that

instead of this 😩
