Dr. Fisch, I am going to do an invitro cycle very soon, hopefully begin treatment as early as the end of this month (May 2011).
I will also begin my menstrual cycle at the end of this month.
My question is:

Do I need to start birth control on day 1 of my period prior to injections? The reason why I ask is becuase I don't want to delay a cycle simply because I did not get on the proper medications. I had heard that some women get on birth control prior to an invitro cycle. I want to be able to time my menstrual cycle and my medications accordingly.
Thank you
for your time.
