What's wrong?

So for maybe a little over a week I've been having some weird discharge, it's like clumpy and thick and it smells weird, I'm not getting any itching or irritation so I'm just wondering what it could be. I had protected sex with my boyfriend a week ago who doesn't have any stds so I don't think it's that I'd just like a few opinions before going to the doctor
