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: My height is 5 feet 3 inches and weight is 68 kgs.

Hello, I have gone through your query and understood the concern. The fact that you always need to be induced to get a period makes me think that you are probably not ovulating naturally. A proper clinical evaluation is needed before initiating medication, more so, as you developed ovarian hyperstimulation with induction. Also, it is important to stay with one doctor whom you find comfortable. Else, your treatment gets haphazard. Metformin is often used before trying induction to see if natural ovulation is possible thus avoiding unnecessary HSS. You are overweight and need to maintain a healthy lifestyle. Taking progesterone in the latter half of the cycle in micronized form is safe. A maximum of six cycles with proper monitoring is given for induction of ovulation. Gonadotropin or Chat Doctor is the medication given to facilitate ovulation. Follicles in different stages of maturity can be seen but cannot be differentiated if they are from a previous cycle. Hope this helps.
