HELP PLEASE

Caitlyn
I'm on day 32 of my cycle when normally on 28 day cycle...no sign of period any time soon when normally I cramp bad 5-7 days before my period I took a test yesterday negative... So my question is... Has anyone else ever been 3 days late and still got a negative test but was pregnant? We've been trying for the last year and 3 months and I'm starting to get discouraged...
