You might not want to hear this but I really think there is nothing you can do, or not do, that will make an iota of difference. If it is a good embryo and your lining is good, it will implant.

There are a million stories out there saying do this, don't do that...and a million more saying do or don't do the exact opposite.

I know you want to be able to influence the outcome but I really don't think there is anything you can do to change things.

If it's meant to work it will. Which, if you think about it, is comforting because it means there is nothing you can really do to prevent it working either iykwim.

Good luck!
