giardiasis, food poisoning or stomach flu/bug?

So about a day ago I started having watery diarrhea, it started off brown now its bright yellow and it looks like tiny shreds, even undigested food (I have been getting back into a fiber heavy diet though). My stomach is bloated and gurgling loudly and painful, and I’m running to the bathroom every 5-10 minutes. I even lost control of my bowels in my sleep which has never happened. I also have sulfer-y frequent burps. Idk if I got food poisoning off of some meat or giardia off of the old tap water I drank in the fridge. I can’t currently run to the doctor right this moment and want to hear any possible feedback?

It’s hard to tell as it’s only been a day, it could be anything. You need to wait and see. It could be giardia, it could also be celiac disease as you said you’ve been eating a lot of fiber rich foods lately. Are you still unwell or has this resolved?

Well it’s been 3 months since I posted lol, yes it passed after starving myself and going slowly on BRAT, took about a week. I started to get it again a week ago (luckily just the beginnings of it but it stopped) but I THINK it might be onions as those have been recalled recently.
