1 Work out the length of your average menstrual cycle. Day one is the first day of the menstrual period and the last day is the day before the next period begins.  Ovulation happens about two weeks before the next expected period. So if your average menstrual cycle is 28 days, you ovulate around day 14.
To calculate the number of weeks you are, you simply start with the first day of your last menstrual period, also called LMP. So if the first day of your last period was January 1st, your first week of pregnancy is January 1-7th, though you are one week pregnant on January 7th as you complete the week. 1  January 8-14th would be the second week, two weeks pregnant on January 14th. Your doctor or midwife may even count days.
