I am 26 and my husband and I are trying to have a baby. Before we decided, I finished my pack of bill control (which i have been on for 10 yrs), had my period, and started a new pack taking Sunday and Monday...then I stopped. I had some light bleeding 7 days later (only for a day or two). How do I know when I ovulate, from the date of my last period or now with that light bleeding? Thanks!
