Hello all! 38 trying for my 1st!!

Im doing letrozole and trigger shot. This is the third round. Went for my scan this morning im on cd 12. I have 3 growing yay! They are smaller than usual though. Two on my right at 12 and 11. The one one my left is at 11. My dr said to cross our fingers they keep growing! I am triggering on wed which will be cd 17. Anyone out there have experienced this? She is estimating the day. I cant afford another ultrasound in a couple days..ugh
