Never trust a fart

Can someone help me out or tell me if they’ve experienced similar?!

I’m very early along, 4 weeks and 1 day. I have had watery diarrhea for the last 4 days 😭😭

SO BAD I can’t trust a fart lmao every time I eat I have to run straight to the bathroom. I’m trying to stay as hydrated as possible but drinking water kinda makes me want to gag at this point. 😅

Also my midwife said it’s not an uncommon early pregnancy symptoms and suggested the brat diet(banana rice apple sauce and toast) but I just started this morning so no improvement so far.

So if anyone has any suggestions on what can help, what I can drink that won’t make me gag, or if anyone else experienced this that would be great 😂
