Follicle size

Im on my first round of clomid and I had my first follicle scan yesterday morning. I had 4 show up. One was on the right and was tiny. Like 5x3. Then in the left I had 3 . One was 12x12 and the other two were 7x7. It was cycle day 10. I go back Monday to see how big they are. They said I had one promising egg. I was hoping for more but I guess one is better than none. Thoughts?
