I'm 2 weeks late for my period, I have darker nipples and my nipples are also sore, I have a discharge and have been farting a lot more recently, I also feel sick all the time and have headaches also. But I have taken two home pregnancy testa and they have come up negative. I want to kow why thwy are negative and could they be wrong?

Maybe I lack the hormone to get a positive result

If you lack the hormone for the teast either it means you are not pregnant or it is too early
