Depends...per WebMD (, "The menstrual cycle is measured from the first day of menstrual bleeding, Day 1, up to Day 1 of your next menstrual bleeding. Although 28 days is often cited as the "regular" cycle length, only 15% of women actually have such a cycle." * A teen's cycles tend to be long (up to 45 days), growing shorter over several years. * Between ages 25 and 35, most women's cycles are regular, generally lasting 21 to 35 days. * Around ages 40 to 42, cycles tend to be the shortest and most regular. This is followed by 8 to 10 years of longer, less predictable cycles until menopause.

How many weeks pregnant are you if you three days late from your period?

4 weeks and 3 days as long as you have a normal 28 day menstrual cycle. It could be less if you have an irregular ovulation cycle.

What should you do if you only had a one day period?

If its your first period or your irregular its normal but if your not irregular it might just be spotting go to the doctor just in case.

When you do calulate your last period to the next?

The first day of your period is day 1 of your cycle, you count from this day up until your next period - this is one cycle. You should calculate the average of your last 6 cycles; add together cycle lengths from your last 6 months then divide by 6 to get your average. Web sites or phone apps can do this for you. The average menstrual cycle is 28 days but everyone is different and up to a weeks difference from your average menstrual cycle is completely normal. It's worth noting that irregular cycles are normal throughout your teens, and things such as ill health, stress, or some medications can effect your cycles. Learning to recognise changes in your body throughout your cycles can help you determine when your period is due, even if your cycles are irregular.

Is it normal to have your period for 2 days only every cycle?

Yes. A period as short as one day is considered normal.

If my period is irregular by FIVE oR SIX days would that alter when you ovulate?

Yes. But you need to know that not every woman has a 28 day cycle. That is just the "average." I know women who have 30 day, 27 day, 42 day and other day cycles. It is just what is normal for you.

What would you have if you had your period every other week had headaches and sleep a lot?

Sometimes periods get irregular or develop a strange cycle. You should see your doctor because it can develop into anemia. Docs can prescribe meds to get your period back to a 25 day to 32 day cycle instead of a 14-16 day cycle.

Can you still ovulate if you only have a 3 day period?

Yes, it is possible to ovulate with a 3-day period. The length of your period does not determine if you ovulate or not. Ovulation typically occurs around the middle of your menstrual cycle, regardless of the length of your period.

It is a bit long, but if you are just starting it is normal. You may also find that you are irregular for a while until your body settles down.

Is there a possibility that a woman can be pregnant and have a normal period if she had intercourse 2 days after her period and her cycle is normally 35 to 40 day?

Although strange things can happen, it would be extremely unlikely given the combination of a very long cycle length and the apparently normal period.

Paragard IUD and you are 32 days past period with negative hpt?

A 32 day cycle is a normal variation in cycle length. Pregnancy is not likely.
