Messed up ovulation & pregnancy?

The link to your chart on fertility friend is wrong, you need to go to home page setup and you will get the link there so that you can share your chart with others. It certainly sounds like you could be pregnant but these symptoms can also be related to your period coming. However it sounds like implantation occurred hence the pink discharge. Wait a few days and re-take a pregnancy test because HCG (pregnancy hormone) doubles every 24-36 hours, if you are still getting a negative result then have your doctor do a pregnancy blood test. Good luck and baby dust!
