The morning after pill aka (plan b) can effect your cycle dramaticly!!! A bleed every two weeks is not normal. It means you have a hormonal balance and will probably mean you are getting low on iron. Go and see a doctor. They will probably put you on the pill for a couple of months to get your system stabilised. None of these bleeds you have will be a "proper" period. A period usually comes after the egg has been released and not fertilised. Two weeks is not longer enough for this to happen, and therefore it is your hormones going a bit haywire causing the bleeding.
NO.
Not normal. It would be best if you saw your doc.
It can cause irregular periods.
especially in your first year of having periods, you will find them irregular. after a year or so, they should settle down to a cycle of one period approximately every twenty eight days. Of course, some girls/women get a period every three weeks and others have one every five weeks; but some people never settle into a regular cycle. keep pads/tampons always at hand, especially if you are having irregular periods.
This is normal, ovulation takes place up to 2 weeks prior to you having your period.
Bi-Weekly = every 2 weeks - Every payroll period will cover 2 weeks. Bi-Monthly = 2x per month - Every calendar quarter will have one payroll period that has 3 weeks in it.
