I had been using the nuva ring birth control, and my doctor told me that there were two ways to use it, 1) keep it in for 3weeks and take it out the fourth week to have a period and repeat or 2) leave it in for the whole month and the period may or may not come (which is what I had been doing). So I took my birthcontrol out and had a normal period and then it stopped. I ve left it out but haven t had any period for 75 days. I thought that I could be pregnant even though the tests said no so i went to the doctor and sadly i wasn t. He prescribed me progesterone to start my period and another round of birth control. I need to know what to do in order to be fertile.. Any advice would be so amazing I ve got baby fever like crazy.
