How does this medication work? What will it do for me?

They help to prepare the uterus lining so that a fertilized egg can be implanted (attached to the uterus) and to maintain a pregnancy once a fertilized egg has been implanted.

How should I use this medication?
Vaginal gel: The recommended dose of progesterone vaginal gel is 90 mg (one applicator) inserted into the vagina once or twice daily, starting the day of embryo transfer. If pregnancy occurs, treatment may be continued for up to 12 weeks.
To insert progesterone vaginal gel, hold the applicator by the thick end and shake down to ensure the contents are at the thin end. Twist off the tab and gently insert the thin end of the applicator into the vagina while you are in a sitting position or when lying on your back with your knees bent. Press the thick end of the applicator firmly to deposit the gel. Remove and discard the applicator. Applicators are intended for a single use only.
Vaginal tablets: The recommended dose of progesterone vaginal tablets is 100 mg inserted into the vagina 2 or 3 times daily starting the day after egg retrieval. If pregnancy occurs, treatment may be continued for up to 10 weeks.
To insert progesterone vaginal tablets, place one tablet in the space provided at the end of the applicator. The tablet should fit snugly and not fall out. While sitting, standing, or lying on your back with your knees bent, gently insert the thin end of the applicator (the one containing the tablet) well into the vagina. Push the plunger to release the tablet. Remove and discard the applicator. Applicators are intended for a single use only.
