White flow?

I'm getting a milky white discharge and I am 7dpo. It also leaves a white stain on my underwear which is also strange for me to see. (Sorry if its too hard to see. Its whiter in person.) It's not a yeast infection. I've had several of them and I know my body and it's not an infection. I know it's common to have this discharge after conception and I've never experienced this before. I was wondering if any of you experienced this same type of discharge as an early sign of pregnancy. I'm trying not to get my hopes up. I would appreciate the help. Thanks :)
