Do you get your period twenty eight days from when you start or finish?

Not everyone starts every 28 days. If you think you are pregnant, take a home test or go see a doctor. The doctor may give you a blood test, they can detect pregnancy earlier than a urine test. If you get a negative result with the home test, wait 5-7 days, if you haven't gotten your period take another one. If after two weeks you still havne't gotten your period and the home tests are all negative, you should call a doctor, you may need medications to get it started again. That happens in some women occasionally. Your cycle will start on the first day of actual bleeding, not spotting. And not all women have 28 day cycles, nor ovulate on cycle day 14.


How can you calculate the safer period for getting pregnancy?

Get a calendar. The first day of your period is day one on the calendar then number each day after to day 28 if you have a 28 day cycle. On days 14-16 in a 28 day cycle ovulation usually takes place. Sperm can stay alive in the uterus for 5-6 days so you have to take that into account. So, if you had sex on day 12 of your cycle you could get pregnant because the sperm would be present when you ovulated.


You had two periods in a row Jan 23-28 and Feb 8-15. when should your next one start if you have a 28 day cycle?

You had two periods in a row, January 23 to 28 and February 8 to 15. Those two periods were quite close to one another. If you have a 28-day cycle, your next one should start on March 7 or 8, depending on whether February had 28 or 29 days.
