I had got the shot to treat gonorrhea, then 8 days later started the antibiotics orally i finished my antibiotics and had unprotected sex on the last day of my treatment (the 7th day) it was 2 hours away from being the 8th day did i infect my partner?

Little or no risk. You were unable to transmit gonorrhea within 24 hours of the shot. The second antibiotic (doxycycline) was to treat chlamydia, which commonly accompanies gonorrhea. That too is cured within the first few days and cannot be transmitted after a week or so. Of course if you were having sex with he same partner before, no sex until and unless he also has been treated. Good luck.
