Your doctor will take a blood sample to detect whether you're pregnant about 10 days to two weeks after egg retrieval.

  • If you're pregnant, your doctor will refer you to an obstetrician or other pregnancy specialist for prenatal care.
  • If you're not pregnant, you'll stop taking progesterone and likely get your period within a week. If you don't get your period or you have unusual bleeding, contact your doctor. If you're interested in attempting another cycle of in vitro fertilization (IVF), your doctor might suggest steps you can take to improve your chances of getting pregnant through IVF.

The chances of giving birth to a healthy baby after using IVF depend on various factors, including:

  • Maternal age. The younger you are, the more likely you are to get pregnant and give birth to a healthy baby using your own eggs during IVF. Women age 41 and older are often counseled to consider using donor eggs during IVF to increase the chances of success.
  • Embryo status. Transfer of embryos which are more developed is associated with higher pregnancy rates compared with less developed embryos (day two or three). However, not all embryos survive the development process. Talk with your doctor or other care provider about your specific situation.
  • Reproductive history. Women who've previously given birth are more likely to be able to get pregnant using IVF than are women who've never given birth. Success rates are lower for women who've previously used IVF multiple times but didn't get pregnant.
  • Cause of infertility. Having a normal supply of eggs increases your chances of being able to get pregnant using IVF. Women who have endometriosis are less likely to be able to get pregnant using IVF than are women who have unexplained infertility.
  • Lifestyle factors. Women who smoke typically have fewer eggs retrieved during IVF and may miscarry more often. Smoking can lower a woman's chance of success using IVF by 50 percent. Obesity can decrease your chances of getting pregnant and having a baby. Use of alcohol, recreational drugs, excessive caffeine and certain medications also can be harmful.

Talk with your doctor about any factors that apply to you and how they may affect your chances of a successful pregnancy.
