i took my birth control the whole month of may, had my period but I started the next pack a week late, so I had the 7 days of sugar pills and than 7 days without pills, my question is do I need to be worried about ovulating in may, or should I ovulate in june since I took the whole month of mays birth control? The ovulation calendar said I would ovulated May 24-26, but I was on my period may 11-18.
