Me and my boyfriend had sex the day I was supposed to start my period but now I am 6 days late.?

If that was the only day you had sex in the past month -- nothing is wrong. You are late. It happens from time to time. You certainly didn't instantly get pregnant the moment you had sex and that caused your period to fail to arrive. If you had sex earlier in the cycle, you could be pregnant and would want to test. (And not clear why your boyfriend doesn't like to ejaculate during sex. What's the point?)
