iui cycle #1

Hello ; I've been ttc for 2yrs now .. 1 year with no medication & 2nd year with Letrozole 7.5mg in between I did get pregnant but unfortunately had a miscarriage in august , we decided to do iui I just had my first iui with Letrozole on nov 28/21 .. 3dpo I know it's super early and I duno I just feel super discouraged already and feeling low about this 😪 even though I was so excited .. Somedays are just really hard? Has anyone is the same timeframe as me for iui or has any success stories? Or any symptoms they have after iui.
