Hi, ladies. About to start our second cycle and my doctor (decided to stick with the same doctor as he genuinely thinks we have a strong chance to have a baby through <a href="https://glowing.com/glow-fertility-program">IVF</a>) is changing my protocol to a higher dose of Gonal, 300 vs. 150 before. He also wants me to take Estrace starting next Sunday up to CD1. Any of you experienced the same protocol and was it successful? Also what would Estrace do and help with exactly? Thanks in advance! Really appreciate all of your advice!
