I doubt you are pregnant, and while you did take the steps by using a condom to prevent pregnancy and stds, now that you are having sex it is time to start birth control. and remember, birth control will not protect you from stds so, still use a condom. Best of wishes!!
Extremely extremely doubtful you're pregnant. Your period is likely late due to stressing about it.
Highly doubt your.pregnant.
Wait a couple more.weeks, if it doesn't come, take a test.
Doubtful that you're pregnant.
