For many couples, conceiving a child may take longer than initially expected. However, infertility refers specifically to the inability to become pregnant after a year of attempting. For women 35 years old or more, the amount of time is 6 months. If you find that you have been trying to get pregnant for this amount of time or longer without success, it may be time to reach out to a fertility doctor who can offer the insight and experience you need to decide on a reproductive treatment plan that can help.
