Follicle size?

Meghan

New to the game here had my first appointment with the RE today .. they did an US and showed I had 1 follicle measuring at 10.something(I cant remember the exact point) today is cycle day 11 for me on my second round of clomid last cycle I ovulated on cycle day 20 .. I’m going back Thursday for another ultra sound but I’m just wondering if that’s a normal size or if I should be concerned ? Doc said it should grow about 2mm a day ...
