Is there any truth to dark lines meaning twins?

k🌻

This is my 6th pregnancy and hopefully 3rd healthy baby (first 3 miscarriages). I’ve taken alotttt of positive pregnancy tests, I think I got a little addicted to taking them but I have never ever gotten a test this dark! The pregnancy line is darker then the control lines, both taken in the afternoon because who can wait till morning 😂🤷‍♀️ has this happened to anyone else?
