If you are doing the FSH treatment as I am plus and IUI or IVF, one needs to start taking Lupron on the 21st day of the cycle. Then about two weeks or so later you will get your period. You are then to go for blood work and an ultrasound (blood work on 2nd or 3rd day/ultrasound on fourth) Once you have had yur ultrasound then Gonal-F is introduce. You continue to take the Lupron.
Lupron surpresses your hormones from releasing your eggs as they mature with the Gonal-F. While on the medications depending on your doctor you will have to go for blood work and ultrasounds every three to five days (I go every four days for blood work and every five for ultrasound). Once your eggs are matured enough then you are to give yourself the Ovidrel and approximately 36 hours later you are either having an IUI or having your eggs extracted for IVF.
Take Care and have a great weekend
