Hello, I am currently taking Desogen in order to start IVF. In March I first started taking Desog en for 2 weeks and stopped on March 17th, so that my period could start March 24th. It did, but now it was discovered I have to have surgery to remove a cyst and fibroid. I was told to remain on the Desogen, but now, my period did not come on the 24th of this month. Was I suppose to stop it on the 17th and restart it again? I have never used birth control. YYYY@YYYY
