The luteal phase of the cycle consists of monitoring of blood levels of progesterone, estradiol, and BhCG (pregnancy tests). If there is a positive pregnancy test, close monitoring of the early pregnancy is highly advisable. We continue to perform the blood tests plus the first pregnancy ultrasound for detection of the baby's heartbeat and evaluation of the number of embryos implanted. Thisc is usually done between the 4th and 6th week post transfer.

In vitro fertilization may not be successful in the first cycle and patients are encouraged to talk to their physician and to actively participate in planning for future treatments. The treatment cycle allows us to gather an enormous amount of information that is frequently beneficial to tailor a patient's future treatments.
