IUI Questionssss ???

We’re scheduled for IUI in September and of course (🙄) everything has been off this cycle.

Normally I am NEVER a day off when it comes to my period but this month I started 10 days early??

I’m also taking ovulation test everyday this past month and for the last 9 days I’ve been getting the blinking smiley face but never a peak one. Even on my period that started Saturday I’m still getting the blinking smiley faces ???

Could it be the SIS that made my period start early?? Should I still start my letrozole tonight since it’s day 3 of my period??

Idk why this is happening this month 😭😭

I’m usually spot on with everything and we’re doing IUI bc of my husbands motility and now I feel like I’m all off.

😭😭😭😭
