Trying for first baby

My husband and I have been trying to conceive for a few months but so far nothing's happened and it's disappointing. I'm pretty young. Only 23. We stopped using condoms over a year ago. But just recently started trying to get pregnant. Should I get tested to see if something's wrong or just keep trying. My period is 4 days late now but  I'm afraid to test because I don't want another disappointment
