IUI #2 Baby #2

Today's finally here. Day 1 my period came early this morning! Called our clinic and now we have to drive 8 hours to our clinic tomorrow to be there for Monday so that we don't miss out on our day 3 scan. I'm extremely nervous this time around. Our last IUI was 2022 with our baby boy, but this is our last vial of sperm so I'm so scared of a negative outcome, I am staying positive, just so nervous. Has anyone had there luteal phase be 10-11 and have sucessful outcomes with a pregnancy? I noticed my period comes 10 days past ovulation now the past 6 months
