Some girls have not have a period within months or years, when should they start birth control?

My girlfriend wants to start soon, but she have not has her term in fairly some time. This is not only her, but a few of her friends (not close-close friends) enjoy the same issue. Can she basically start taking it when she wants?

There are many reason for irregular periods, or total amenorhrea (not getting it at all). Sometimes it is only fairly usual variations between one woman and another, but scarcity of menstruation can also be a symptom of an underlying problem which needs treatment.
This should be evaluated, to rule out conditions that could be potentially negative.

You can not assume that she is infertile. She could still ovulate, even without regular period. Ovulation always comes first, later the bleeding about 2 weeks next, so you never know when that could happen.

Anyone who is sexually helpful should be using some time of birth control unless you are planning to be pregnant.

My sister-in-law: no period for several years . . . needed fertility drugs to obtain pregnant twice . . . then BAM adjectives of a sudden pregnant 13 years later at the age of 40. THIS REALLY DOES HAPPEN!!

Use protection, NOW.

Additional Info -- OH, OKAY!
No, she does not stipulation to wait for her interval. There are two reasons for starting near the period. First -- to be sure she isn't pregnant, which contained by this case isn't called for. And second -- so that it won't disrupt the cycle, which doesn't apply since she is already irregular.
She can start anytime.

Do you believe you can always carry what you want?

she has to see a doctor and she requirements to discuss this, most likely shes adjectives herself which is popular these days and that will stop the mensus because she hasnt the extra blood to lose. shes slowly massacre herself if thats the case.

no she shouldn't start until she goes to a gynecologist to find out why she hasn't have a period, if it hasn't be a long time since she first started its normal to miss a term or be off calendar, being althetic, stress or hormone balance are a few reasons especially if she's young- birth control resembling the pill or ring is used on a schedule beside the cycle (like sunday after the period ends)..if she's have a period already she can still bring pregnant at any time-- a doctor can see whats going on if she lets them know everything almost her lifestyle and find whats the best kind pills or doesn`t matter what type she wants to use for her
