So I had an SIS with follicle scan last week and was told I would be ovulating soon. I had my first round of letrozale too. He said I responded because I had 2 follicles. I have been checking with ovulation strips and only show high..no peak yet. Has anyone had an SIS prevent them from ovulating. I am trying to figure out what is going on because the Dr. for the procedure was so hateful and negative I will not be going back to him. Any insight would be greatly appreciated as I will be finding a different fertility specialist..female this time.
