Pregnant women should NOT suddenly stop using progesterone!

Important Message

If you have been using progesterone in order to get pregnant and you are successful, DO NOT suddently withdraw the progesterone cream. A sudden drop in progesterone levels may trigger a miscarriage.

Regular dosage can be maintained and gradually increased to 80mg right through until the last trimester. At this stage the placenta is well and truly producing adequate levels of progesterone to maintain the pregnancy. The baby’s placenta takes over the production of progesterone at the beginning of the second trimester, and this is when a miscarriage is likely to occur if this production is not adequate.

Women with a history of miscarriage or premature delivery choose, for their own peace of mind, to continue using progesterone through to the week prior to expected delivery. The placenta is producing such huge amounts of progesterone that any extra progesterone over and above will not harm mother or baby.

Women with a history of ‘high risk’ pregnancies are encouraged to continue progesterone supplementation up until delivery. However, Dr Lee warns that should you decide to stop applying progesterone, make sure you wean off your dose ever so gradually.
