Question

yeah 21 days after the last one!

Not worried at all im trying to figure out if il be on my period when im on holiday!

JUST REALISED THIS IS UNDER THE WRONG CATEGORY WOOPS!

Answer 1

well looking at this from a logical point of view rather than from a woman's prepective;

If your period starts 21 days from when the last one ended, assuming that your period last 5-7 days, this would give you a menstrual cycle of 26-28 days.

But I'm a guy so what do I know eh!

Answer 2

This, some-what of an easy question but i find myself laughing slightly not because of your question bur because i was asked the same question today as i am every month.
Medically speaking your menstrual cycle should occur every 28 days. However in saying this it can deviate alot from person to person.
If you are normally very regular and begin your cycle within a couple of days either side of 21 days use the 21 day cycle as your gauge.
Problems can occur if u do not have a regular mestrual cycle for whatever reason then it can be a guessing game as u have to be prepared all the time (just incase).
Fluctuation in your cycle can be due to various causes after childbirth it is very common. However i dont think this will apply to you so usually 28 days between each menstrual cycle.
However, if your own cycle has been different from adolence and remained that way this will be what is normal for u.
Hope u have a great holiday and take care.........

Answer 3

If you were on the pill you would take 21 tablets and then stop for 7 days for your period.
Think this is because a lot of people have a 28 day cycle.
Mine used to be very irregular sometime 6 weeks others 2 weeks between periods, that was normal for me.

Answer 4

Well its supposed to be every 28! But each person varies, I on the other hand from you, get mine only 4times a year, i have seen specailists who assure me that there is not a definite answer to 'how often your cycle runs, although if you wish to regulate your period, you can take the pill, insuring you are in control of the cycle!

Answer 5

28 days is the standard, but not everyone is standard. I used to get my period for 2-3 weeks at a time. If you are concerned about it, talk to your doctor and get on birth controll. It helps regulate you.

Answer 6

Is it 21 days AFTER the end of your last one?
In which case start to start would be 28 days.

Edit: Pretty much what jazzman just said c'mon we're blokes what do we know (other than logic)?

Answer 7

It's 28 days and you start counting from the day your period started.

Answer 10

The average is 28, but if yours is more or less, there really isn't anything to worry about- these figures are only averages, and your body might not conform to them.
