Go to your doctor and tell them that you're worried that you havent had your period yet and it's been a month.
There are the over the counter test kits that state they can tell in 5 days, but I doubt they are very accurate. The missing of a period is a sure indication of pregnancy.
Menstrual periods can "block" whatever you have going on inside you.
No a guy just want be able to tell if you are on a period. Yes, some are able to tell by your behavior.
if they say there sick. if there sleeping/eating alot and if she says her period is late and if shes sad.
If you need to tell your teacher that you have your period all you do is take them to one side and say 'Sir/Miss I have my period' - it's that simple.
You can't since there are always aftershocks but no reliable way to determine how many there will be and over what period of time before they subside.
graphs are used to tell the difference between things; to see how much something has changed over a certain period of time : )
Well, you can tell if you're late by the simple observation of whether or not you actually get your period on time or not..
no it can't tell you if you missed your period for 8 weeks
just tell them i got my period i saw it it was red i think it was blood. it's easy
Ask her.
