@Luckyme1 I am so, so sad to hear your news that it is a BFN. Like everyone here we were all hoping that this was the one for you and that you'd have your lucky last miracle. It must be very difficult to draw the line under it all, but at least you know you've done everything possible and won't look back with regrets - you've done your absolute best.
I'm sure there will be a process of grief and then healing, and I'm sure that the huge amount of love that you have to give to your family and the little ones that come into your care will be returned to fill your heart and heal the scars.
Love and hugs
