I"m 30 years old and never have had regular menstrual cycles so my OBGYN gave me Provera for 7 days which started my cycle then on the 5th day of cycle I started Clomid. I finished the Clomid 5 days ago (10/21/2012) but I have no idea what my ovulation schedule is or how to find out. How do I know when I'm ovulating and when is the best time for intercourse? How long does the ovulation last? Someone please help because I am stressing without knowing. Thank you so much:)
