Is it normal to have cramping before frozen embryo transfer?

It is common to experience mild cramping before and after a frozen embryo transfer (FET). These cramps are usually caused by the medications used to prepare the uterus for the transfer, such as progesterone and estrogen. These medications can cause the uterine muscles to contract, which can lead to cramping. Additionally, the procedure of the FET itself can also cause some cramping as the embryo is inserted into the uterus. In most cases, these cramps are mild and should resolve within a few days. However, if you experience severe or persistent cramping, it is important to contact your doctor to rule out any other potential causes.
