Digestive issues/candida/IBS?

So I’ve suffered from digestive issues, bacteria build up, and chronic candida for the last few years. I changed my whole diet, no gluten or dairy or sugar, and I’ve felt a lot better over the last year especially. However, in the last month or so, I’ve had some new issues arise. I’ve been feeling extra inflamed and my tummy has been a bit uneasy. I haven’t had any diarrhea, but there’s been a few times where I’ve had really bad cramping and had to use the bathroom like five times within an hour or two. Recently, within the last 3 days, I’ve started to have discharge/mucus with a fishy smell coming from behind. I feel like I need to use the bathroom, but that’s all that comes out. (Sorry for the TMI)

I’m just wondering if anyone has experienced this? The one other time I’ve had this was about three years ago before I was first diagnosed with all my intestinal issues. That particular time I was very very sick, I was vomiting and had the worst cramping and thought I had diarrhea but it was clear, and i was basically passing out on the bathroom floor. So I ended up going to the hospital because I knew something was really wrong.

I’m just wondering why this is happening to me now when I’ve been taking care of myself as much as I can. What is it from? Does this sound like IBS or something else? A parasite?
