Had unprotected sex for like 3 mins then he put a condom on. That was July 4th. Period was due July 8th. I took a test on the 16th is was negative. Was it to early? When should I retest? My cycle is 25-27 days long. I did have period June 12th.

Retest. With this history I would assume you are pregnant until proven otherwise or until you have a normal period. Concentrated urines are more likely to be positive early on. Different tests have different sensitivities. I suggest making appt with your family doctor for further evalation and support.
