I first started taking birth control (yaz) on the first day of my last period ( aug 23rd) on aug 24th I became I’ll from a stomach bug and vomited up my pill and had diarrhoea. I didn’t double up on my pill and instead proceed to take it as normal on Aug 25th however for the next few days I had diarrhoea.I had unprotected sex on September 3rd but I did take the morning after pill. Should I be okay and not be pregnant

If you had multiple episodes of diarrhoea daily for a few days it’s best to assume your protected was compromised. Take a test 3 weeks after unprotected sex, the morning after pill isn’t 100% effective.
