HSG and delayed AF

Rachel

Does having HSG done delay AF? I had it done last month on the 10th day of my cycle, I spotted for 2 days and could not BD on the 12th day which I presumed was to be ovulation day. We however did it the next day. Now my period is 3days late. Don't know what to think. Tested the day AF was due and I got a blazing Negative. Been cramping since then but no AF. Should I test again?
