Definition - What does IVF Pregnancy mean?
IVF pregnancy refers to a pregnancy that occurs after undergoing an in vitro fertilization (IVF) procedure. An IVF pregnancy may put a woman at increased risk of certain pregnancy complications, including ovarian hyperstimulation syndrome (OHSS), multiple gestation pregnancy, subchorionic hematoma, and premature delivery.
FertilitySmarts explains IVF Pregnancy
An IVF pregnancy is similar to a pregnancy that occurs through intercourse with a few exceptions.
A blood test to check for pregnancy is typically scheduled for about 10 - 14 days after an egg retrieval. Women are generally not recommended to rely on home pregnancy tests prior to this time as the medications used in fertility treatments can cause a false positive at an earlier date.
Women who become pregnant after IVF may be prescribed progesterone support to help maintain a healthy pregnancy. Hormone levels may be rechecked in a few weeks time to ensure the pregnancy is progressing as expected. Ultrasound confirmation of pregnancy is also recommended after several weeks.
There are a few potential complications of IVF pregnancy. One such complication is a subchorionic hematoma. This is when blood pools within the chorionic membrane of the placenta or between the uterus and placenta. The most common symptom is bleeding in the first trimester of pregnancy. Many times there are no symptoms and a subchorionic hematoma is discovered on a routine ultrasound. They usually resolve on their own but in rare cases, they can cause the placenta to separate from the uterine wall. This could result in preterm birth or miscarriage. Subchorionic hematomas are more common in IVF pregnancy than natural pregnancy. Other risks that are more common in IVF pregnancy are ovarian hyperstimulation syndrome (OHSS), multiple gestation pregnancies, and preterm birth.
Another difference between IVF pregnancy and natural pregnancy is how the due date calculated. With IVF the due date is calculated using the egg retrieval date or transfer date rather than the woman's last menstrual period as a starting point.
