Mucus

So I loose alot of mucus and I can't decide if it is my mucus plug or not. I have been loosing mucus for about 2 weeks now. It's a good amount and either usually white or a more yellow/light greenish color. I have never had a yeast infection and I don't think that's what is going on but I just don't know what is going on. There is no burning or itching. Is this considered normal discharge or is it pieces of my mucus plug? I have one picture of one time that I had my phone with me. But the amount have increased since then.
