I have also read what petite wonder posted. Also it could be old blood perhaps???
I would watch your symptoms. You could take a test if you wanted too now or you could wait it out and see if this turns into a period. I read somewhere that some women get a bit of discharge of a pink/brown nature when it is around their period time even when they are pregnant.
No I didn't my dr told me to wait till I was late.
A tricky situation. Did you do a second test yet?
