Could I have passed oral Gonorrhea or Oral Chlamydia before testing positive for it?

Had an encounter with a couple 160 days ago and performed oral on wife. There were no homosexual acts and i used a condom for vaginal sex with her. She switched off giving us head without a condom. Then 60 days ago I had another encounter with a couples, no homosexual acts and I didnt go down on the wife but she gave us both uncovered head.

I went for an oral swab for Gonorrhea and Chlamydia and it came back negative.

Is it possible after 160 days and 60 days that I tested too early?

Also is it possible for me to give it to someone else if i eat them out but still test negative if i went too early? I think 160 show be plenty to test positive for oral STD and I thought 60 days should be enough time too?
