Question regarding ovulation induction.

In last cycle, ovulation was induced with 2.5 mg letrozole for 5 days from day 2...26*24mm Follicle seen at day 12 on right ovary...HCG 10000 and GnRH agonist injections were administered. At day 14, Follicle ruptured...Took susten200 mg twice a day for 15 days ...On day 28, Got periods. Now, at day 2 of this cycle, 2 simple cysts of size 14mm and 12 mm were observed...My doctor is telling they could be follicles too...So asked me to take 2.5 mg letrozole on day 6 and day 7... My questions are: 1. can follicle size be this huge (14mm and 12 mm) on day2 of cycle? 2. I don't have polycystic ovary... Are these cysts result because of previous ovulation induction cycle? Looking forward for second opinion/ advice on the same. Thanks in advance!
