Follicle Help Please!

MissK
I just had an ultrasound to check my follicles..  The doctor told me I have a 19cm follicle on the left side, and a 20cm follicle on the right.  
​What exactly does this mean?? He told me that the normal size is 18cm and up... Does having two matter? This was my first round of Clomid.  I do ovulate on my own, but was prescribed Clomid because I am 23, have been TTC for 2 yrs... Husband checked out okay.. My doctor felt that Clomid would help boost my odds... 
​I appreciate any input!! Thanks ladies!!
