Nik I have a question for you!

So I have been researching the estrogen priming IVF protocol and I guess I'm wondering when the estrogen is started...some protocols say you start estrogen the day after ovulation so I'm guessing that this would prevent a pregnancy that cycle? I will talk to my RE but I'm just wondering do you have to avoid sex during fertile window that month to prevent possible conception? Looks like most EPP's do not use BCP of any kind.

Any insights you have would be helpful.
