There was a study done on MDL proto.col that discussed older women (35-42) needing to trigger when the average size of the two lead follicles were smaller - like 17mm on average (don't quote me on this number). I just remember it was lower. Found the article. Here's the link if you're interested. You are younger so who knows. Thanks again for the dosage!
