question: Hi. I am Kate. My age is 33 years. I have PCOS and usually need to have a withdrawal bleed. Last cycle i went in for fertility treatment and was treated with 100 mg clomid for 5 days + 150 mg Gonal F for 3 days + 225 mg Gonal F for 4 days and on Day 15 was given a trigger shot. But i did not conceive. I also had mild OHSS. THis cycle i visited another doctor on Day 15 of my cycle. He gave me 60 ml of some injectable to release the egg from a follicle 18 mm in size. he said it is not ChatDoctor . what can it be? Also in the scan he said one follicle is leftover from last time and one is new. Is it possible for him to know this if he hasnt seen the previous scans? He has also asked me to take duphaston 2 tabs from Day 18 to 28. Many thanks - Kate. PS
