Hi all! I feel a bit stupid asking this- should know the answer by now but feeling confused...My clinic is Guys in London. They like people to have one natural cycle after a failed cycle before starting again. I've just had a failed FET and have decided to go ahead again ASAP as we're lucky to have a couple more embryos in storage. Does that mean I notify them on Day 1 of my next period (first natural bleed after the failed cycle) and then start Buserelin on day 21 or do I contact them on the first day of my following period? Any ideas? Just trying to work out some rough dates of when things might fall...Thank you!
