Is there something wrong with me?

For a whole year straight my boyfriend cam in me. We did it every day or every other day and I never ended up pregnant, is there something wrong with me? We were not trying to get pregnant and he said whenever he cam he was really stressed because he didn’t want me to get pregnant. But now we are trying for a baby so I’m worried that it won’t happen for awhile 😦 could it be from him being stressed?
