Letrozole round 6

Hello everyone , today is cycle day 8 , I went to gyne for a follicular scan and it’s look like right now I have developed 2 follicles 10 mm each of them . She said is too early and come back on Monday , which will be around 4 days , do you think the follicles will be enough big by then ? Anyone have experience with it . THANK YOU MOMMAS , wish luck to everyone
