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 OHSS. 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 hCG 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.
