how many people had 1st failed IVF attempt and 2nd worked??

Jessica
Any tips for the second round?? They are letting me go straight into it. The first one just didn't take. We did genetic testing on the embryo, I don't have any issues. We did IVF because of low sperm count. I'm just so defeated. I got pregnant though the first try I did IUI but miscarried. At least I got pregnant and know I can.
