Discharge always has a green tint.

And before y’all tell me it’s an infection, BV or an STI/STD. I’ve been tested constantly. There’s no smell it’s normal consistency. All that. No pain itching or discomfort. I have struggled with BV in the past. It’s finally resolved in the past few months after getting a new partner. We’re both clean. I’ve had a lot of tests from my gyno and all of them come back clean. I get my annual paps bc I’m higher risk for cancer. Could it possibly be my birth control has changed the color? I’m on nuvaring and I’ve noticed it the past few months esp right before my period like today. It had a green tint. I’m all lighting. But no smell so it’s not anything bad. I take probiotics and drink plenty of water. Wash outside with water and unscented soaps. Idk. It’s been like this for months. My gyno has gone though all the tests with me. They’re very thorough unlike my old gyno. Is there something they might be missing? Or can this just be normal for some women? It’s not bothering me at all anymore. It never really has but I’ve always been told that even a slight tint of green is bad.
