I took this this morning at 15dpo and I'm not sure i waited long enough because i was so discouraged with not seeing anything. The window was still pink, and not white if you know what I'm talking about?)

Anyway I went back and looked at it and saw a fait little line, it looks pink to me burn think its just an evap, what you you girls think?
