What does it mean if you don't have your period in 2 or 3 weeks ? IS IT SCARY?
if you are sexually active it may mean you are pregnant. if you are not it could be a number aof things, it does depend on how long you have your period for, if their are regualr and stress plays a huge part in when you get your periods and if you are on any form of contracpetion, hard to answer with no information - i think you should see you doctor just to be safe.
ooooo you are pregnant girl. hope you like kids
how old are you?when did it start/=this question is kinda hard to answer without some more information=sorry
Depends. Some women have irregular periods. I have sometimes skipped a month, occasionally skipped two months, but it always comes back. If you are having intercourse, wait another month and if you don't start, get two home preg kits and test yourself twice. If either one says you are pregnant, make an appt with an obgyn and confirm that you are or confirm that the home test was in error.
If you're young don't worry about it. When I first got my period I didn't get it again until 2 months later. Your cycle can be irregular in the first year.
