So I am 9 days late on my period. Last pregnancy test I took was on Sunday morning and it was a digital. It was negative. I have been experiencing cramps, milky colored watery discharge and fatigue. I could have sworn I had implantation bleeding a few weeks ago when I wiped (it was brownish/pink in color). Is it possible to still be pregnant but never get a positive test? I just don’t know what to think at this point. My periods have never been irregular before...just need advice I guess.
