How long should you try to get pregnant before calling your doctor? Most experts suggest at least one year. Women 35 or older should see their doctors after six months of trying. A woman's chances of having a baby decrease rapidly every year after the age of 30.

Some health issues also increase the risk of infertility. So women should talk to their doctors if they have:

• Irregular periods or no menstrual periods
• Very painful periods
• Endometriosis
• Pelvic inflammatory disease
• More than one miscarriage

It is a good idea for any woman to talk to a doctor before trying to get pregnant. Doctors can help you get your body ready for a healthy baby. They can also answer questions on fertility and give tips on conceiving.
