Odor smell questions.... Tmi help!!!!

Ok so I have never ever had this before! I have never smelled! Well I started taking fish oil three times a day it's in the vitamin packs I take. And the past week I have noticed a odor, my discharge is normal no ducky color like yellow or green or anything. Just a fishy smell...... Could this be from taking fish oil and krill oil pills everyday?? I have no itching or buring or color changes or bumps in my vag just this smell and it's driving me nuts!!!! Help please!!!
