@Magix86 @AMMxx re: breastfeeding my clinic aren't supportive of breastfeeding, so they didn't know, which sits a little uncomfortably. The reason they gave for stopping breastfeeding wasn't safety concerns or success rates, but that if I achieved a pregnancy my supply might drop or stop which is an odd argument (wean your child which isn't an easy thing to do, because you might need to wean your child if you're pregnant which isn't even a garauntee🙄).
I spent quite a bit of time reading about it before going ahead. Both times I've chosen to wait until my period has returned (around 14months post partum each time) before doing treatment, and it was a medicated FET both times, where the medication isn't contraindicted for breastfeeding (though can affect supply - though to be honest I've not noticed any noticeable dip in supply during the TTC part either time). I think its a bit different in you're doing stims, as there is some medication, such as letrozole for example, which is not safe to take during breastfeeding, because there is good evidence it enters your milk in higher quantities. The research around breastfeeding and IVF isn't well researched though,but there are some small studies suggesting it doesn't impact success rates. I think its very much a personal choice though. And I had some horrible breastfeeding aversions during pregnancy so stopping has some advantages I think. On the otherhand, in my situation where my transfer didn't work, I can still continue to breastfeed my son without putting him through the disruption of weaning, when the transfer didn't work anyway.
@Magix86 I think I'd concentrate more on the embryo banking and the embryo assurance, than the multiple transfers I think. If you wanted to cut down on the cost of transfers you could do PGTA screening. Its expensive but less expensive than the cost of transferring and embryo that wont work, and would at least mean you know how many viable embryos you have to work with, and might be good for helping to decide if you needed more than 2 egg collections to bank enough viable embryos? Though I think the flip side is then on how you would feel at the other end if you were having to destroy an embryo thats viable. P.S you CAN donate embryos made with donor sperm, if there is still a family slot available for that donor in your country (this was something I asked my UK clinic about)
