Dear Joy, I am not bothered at all by the questions. Only in this case I am not sure I have the right answers.
When I did have cysts (not often) I haven't managed to grow a good follicle, but I also got rid of the cysts pretty quickly. So I don't know what would have happened if I stayed with them with high FSH. Now that I think about it, I think I got BCP in such cases. But I am really unable to tell what is right. I even remember my local RE saying once that "I got BCP because of the cyst".
Maybe someone else has more experience with this. Otherwise, I would not self-medicate, I am afraid it might cause more harm than good.
Really sorry I am not able to help... Hope you soon find the right answer. If an RE want to administer BCP and gives you an explanation for it, I would take it. Anyway, hope you manage to get over this soon...
