Curious about others protocols

I have gone through ivf and 2 fet. My sister has gone through her first ivf and is in the process of her first fet. We had different drs but our protocols are so different. For my fets I had lupron shots, estrogen patches, sildenafil suppositories and then 2 pills medrol and something else the 2 days before and after my transfer and then progesterone shots. She is only on an estrogen pill and some kind of suppository 2 hours before transfer and then progesterone after. Anyone else’s protocol like hers and successful?
