Period is late

Naoimh

Hey guys,

Basically my period is late by 85 days, I took a pregnancy test and it said I'm not pregnant. I've an appointment next week with my GP to see what's up and to see if I've a hormonal imbalance cause the majority of my family think I do. I know I'm going to the GP next week but I'm still freaked even though I took a test.

So I'm asking if theres any reasons that you guys know of that could cause my period to be late by that much without it being pregnancy?
