Test Again?

I'm too weeks late on af. Just really moody, headaches and want to eat. Always hungry, lol... Had 2 bfn... And noticed cm milky, white sticky/stretchy like school glue. Not a whole lot like other posts. I can stretch it between my fingers a couple times and thickens. Sorry tmi. Should I wait till Friday to test again? I want to be with child, but these bfn are discouraging :(
