Don’t smoke, or quit now if you do. Aim for a normal weight if you’re overweight through diet and exercising regularly (Body Mass Index or BMI 18.5 to 25). Use condoms to avoid STDs if you’re not in a stable relationship, and get tested if you are at risk.
Don’t wait too many years to start trying, and if you’re over 35 when you start trying see a Fertility specialist (Reproductive Endocrinology and Infertility or REI MD) if you’re not pregnant after 6 months of unprotected intercourse. See an REI when you’re ready to start if you don’t have a regular period every month, if you have had endometriosis or Pelvic Inflammatory Disease (PID), a previous ectopic pregnancy, or any surgery on your ovaries.
