I am in same boat as yours .if possible ask the girl about her status be stressfree for a bit..and get tested at 28 days using 4th gen test.do test gor all stds
If you inserted with condom break and exposed the head, then you need to test. Only the head needs protection though so if that was still protected you wouldn't have a risk.
A duo is conclusive after 4 weeks so after Aug 1 you can test.
