As you reach your early 30s, your eggs might decline in quality — and you might ovulate less frequently, even if you're still having regular periods. An older woman's eggs also aren't fertilized as easily as a younger woman's eggs. Does this mean you can't get pregnant? Of course not. It might simply take longer. If you're older than 35 and haven't been able to conceive for six months, consider asking your health care provider for advice.
