I feel like I’m having a digestive problem and I’m confused and concerned?

So I feel like I’ve been having weird stomach/digestive problems for more then a month now this started just last month in June and I can’t seem to figure out what it is I’m going crazy it started out with feeling bloated all the time with some yellowish direah this lasted for a bout 1-2 weeks it felt like I needed to fart to relief some gas, I didn’t go to the doctor Because i started to feel a little better slowly and during the time of my problem I did change my diet to very healthy foods such as leafy greens and beans and more fiber and exercise, but as of right now I don’t have anymore bloated or dirreah i feel normal I think , I have been doing regular smooth poop color brownish/yellow sometimes these past weeks does my poop look normal?..Here is a pic
