انا الي الي مجوزه حملت في الشهر الثامن ونزلتو ببدايه الشهر التاني انا

From your description, your period is reasonably regular and those two days of early or late start of your period are not significant. The ovulation usually takes place 14 days BEFORE the start of your next cycle. For example if you expect your period to start on the 1st of December, then the ovulation is around the 17th of November. But, and this is the important, if you and your husband are together every day, there is NO reason, for you and your husband to worry at all about the day of ovulation. I advise you to have intercourse two to three times every week, and this should be OK. After few months if pregnancy does not happen, I advise you to see a doctor. Regards
