Yeast infection?

So recently I tried a different lifestyle as a Pescatarian (only eating fish and veggies) when I changed to this lifestyle, I was on my period. I only tried it for a week bc I did not like the way it was making me feel. However, my period now last 3-4 days. Now with this being said, whenever I discharged, I've NEVER had a scent. Since coming off my period and ending the Pescatarian lifestyle, I've now had heavy discharge for now about 10 days. I quit eating like a pescatarian on the 7th day. And my period was ending on that day. Could the scent come from what I was consuming or is it a possible yeast infection? There is absolutely no irritation, it's just a heavy creamy white discharge that has a scent and it's strong to me bc yeah...
