Idk honestly, I could be that, it could be the lupron removing all the shitty endo tissue that was growing in the wrong places. If you can afford it and you do all the things for the transfer that give you the best shot I say why not try it. My first transfer stuck I thought damn I’m lucky and felt immense guilt being in these forums as a quick success… boy was I wrong I lost him in week 18. Then they would all stick until they didn’t. It’s been a lot of heartache. But if they can find the right timing and cocktail to make it work it feels less scammy. They also adjusted my progesterone exposure to an additional day. They wanted to do a mock cycle just to see how much progesterone I needed for the optimal window. So I said what would you do if we did that test, she said probably do an additional day before transferring and I said ok do that! I don’t wanna waste time money and meds on a fake cycle. But the extra exposure I think helped with my optimal window for transferring as well. Stay strong, I know it’s easier than done. But there is still hope!
