Follicles?

Tr

OK I just got measured for the first time after starting my systems which is Gonal-F and centrotide along with menopur. I only show 3 follicles on one side and none on the other. This is day 7 of meds. Is there a chance that more follicles will grow in the next couple of days and in my right to say that these numbers seem really low? Any help is greatly appreciated thank you in advance!
