Almost 3 weeks late

Hi all,

I am now 2.5 weeks late for my period. Tested 3 days after AF was due, negative. Tested 6 days later, negative. Went to my GP that same day (last Monday) and she informed me that it was too early for anything to show on a test so to just wait it out. I am still waiting.... reluctant to take a test as I am having mild cramping which are like period pains. I suffer from endometriosis so I am usually double over and unable to walk when I have pains normally..

Hoping somebody has/had similar stories? x
