I am now 9 days late for my period. Lots of CM for the past 2 weeks. Eating a lot more, more tired, etc. I've also had some cramps but no sign or period at all. however, I've taken 4 pregnancy tests and all have said negative. Should I wait a little longer and test again? Should I make a doctors appointment? What should I do ughh I'm so confused!! I've never been late before.
