Normal discharge 4 weeks pp?

Does this look normal? I keep thinking there’s a yellowish tint to it and I’m afraid that means there’s an infection but it could also just be normal discharge? I’m a ftm and don’t know exactly what everything should look like. I’ve had pieces of tissue come out of me that I’ve never seen before either and I’ve read that that’s normal. I don’t have a fever or anything like that. I have occasional irritation and slight itching but I had internal stitches and the knot still hasn’t come out so I’m assuming it’s from that healing/coming out. And when I go to the bathroom there’s nothing on the wipes.
