PCOD - follicular study, letrozole.

Hi. I was diagnosed with PCOD few months back so I consulted a gynecologist. She advised me to take letrozole 2.5mg from day 3 of period to day 7 (1 per night) and also to undergo Follicular Study & ET from day 14 ( from date of period ) for 2 days. ET size on day 14 is 8mm and follicle size on Right Ovary : F1 - 17x17mm and F2 - 18x12 mm. Left Ovary : MSF. ET size on day 16 is 8.5mm and on Right Ovary follicle ruptured and free fluid present in POD. Left Ovary : MSF . When I visited the doctor on day 16, she advised for estradiol test to be done and the result was 41.8 pg/mL. She also advised me to take Susten SR 300 mg (1 per day) from day 18. Today is cycle day 18. Is everything alright with me? Is the result of estradiol test normal? Are there any chances for me to get pregnant in this cycle. Kindly provide your valuable advice. Thank you in advance.
