Most healthy women under the age of 30 shouldn’t worry about infertility unless they’ve been trying to get pregnant for at least a year. At this point, women should talk to their doctors about a fertility evaluation. Men should also talk to their doctors if this much time has passed.

In some cases, women should talk to their doctors sooner. Women in their 30s who’ve been trying to get pregnant for six months should speak to their doctors as soon as possible. Getting a complete and timely fertility evaluation is especially important.

Some health issues also increase the risk of fertility problems. So women with the following issues should speak to their doctors as soon as possible:

• irregular periods or no menstrual periods
• very painful periods
• endometriosis
• pelvic inflammatory disease
• more than one miscarriage

No matter how old you are, it’s always a good idea to talk to a doctor before you start trying to get pregnant. Doctors can help you prepare your body for a healthy baby. They can also answer questions on fertility and give tips on conceiving.
