Follicle scan


So I had my follicle scan today since taking clomid. The ultrasound showed about 8/9 growing follicles with the largest about 13mm. I've to go back on Friday to re scan to check their progress. She said I must be very early in my cycle. I have no idea where I am as I took the clomid without having had a period so I'm just counting day 1 of clomid as cd3. Does this seem an ok size follicle giving that it must have some growing time between now and Friday?? Also I feel really full and bloated today !!❤️
