Has anyone used ovitrelle injection during a FET cycle? I thought ovitrelle is meant to trigger ovulation so I'm a bit confused why I would need to do this for a frozen transfer. I would need to have an injection 5 days before transfer, then second injection 2 days before and then the last one 1 day after the transfer. It's 250mg pen and I need to divide up into 3 parts but I can only see 1 needle in the pack. I have asked my clinic about this. This will be my third attempt using DD but first time using Ovitrelle. Thanks in advance.
