If she's worried about getting pregnant, the stress alone can easily delay her period.  Remember protection is not 100\n%.  you can experience condom failure.

Unless she tells you, you won't know. If you have sex with her, and you notice that she bleeds, she may be. But even then, she might not be, it may just be her second or third time.

Women are really horny during their periods actually. And you should wait 2 days after she has finished her period so about 5-7 days after it's started.

No it will not effect her period.  She will get her period when her body is ready.  Might sound bad but at least she is masturbating instead of being sexually active.  She is way to young for that so this is alot better for her.

Same girl,.... bleeding each time - somethin's wrong - go see a doctor.  Some girls bleed their first time, but every time? \n\n If you are suggesting that you are sleeping with multiple girls and they all bleed every time,..... I fear for you!   You may be too large, and will blow-up and it will fall off!   LOL (which would serve you right, for not being monogamous.)

If your menses have always been this way then it may be "normal" for you.  Sometimes bleeding will change in amount, but hasn't completely stopped.  If I count your days correctly, this is about a week.  Some womens' menses last a week which is normal for them...If you are concerned talk with your gyne about it...\nGood luck...

Sounds like what you are descibing is spotting.  Definitely call your doctor though.  It could be as simple as rough sex that caused the bleeding, or it could be a sign of an STD, or an infection down there.

I don't bleed, never have.\n\nSome girls bleed because their hymen is still intact or present. It's nothing to worry about unless it happens all the time, or it happens long after you lose your virginity.

not all girls bleed that's this crazy idea that people have come up with because many girls do.  the hymen, which causes bleeding is not a sign of virginity or non virginity.  they can stretch or tear from many different things, falling, bike riding, tampons.  some girls also end up bleeding much later, or with another partner later on who is larger.  some bleed the second time or the third and others not ever at all.  i second what the other person said hopefully you are old enough to know enough to use birth control... pills condoms etc.

Blood doesn't pour out of you when you have your period. It's just a very slow trickle. In just a few minutes, shower or no, nothing will likely come out.

She is most likely underweight, which does cause women to not get their periods. She needs to see a doctor so she can get examined properly and get the information she needs to get healthy again. If she has an eating disorder (anorexia/bulimia) then she would also need counseling with a therapist.

all girls cycles are different i bleed alot more on than off most are as long as 2-3 months with only 4 days stopped its normal for some to not bleed at all or very light just to be on safe side pop to doctors it may be nothing but might put your mind at ease

lol. Men are cute sometimes.\nFirstly, not all women experience PMS. (They're also lucky women). PMS is also a term many women abuse, by claiming every little thing is stemming from it, when they don't even know what it is, or when ir occures.\n\nIf she is regular, the only way for you to know when she's on it would be to know how long her average cycle is (say 30 days) then count 30 days from the first day she starts on a particular month to calculate her timing for the next month. \n\nAnd lastly, if your girl doesn't tell you when she's menstruating, maybe it's simply because she doesn't want or need you to know. But don't use PMS as an indicator. Not only is it an unreliable one, but it come before menstruation (hence PRE-menstrual Syndrome) and you would have to guess how many days later it comes anyways....

No, not every woman does.\n\nThere is sometimes some bleeding because Females have a hymen (slang name "cherry") which is a thin membrane that partially covers the vaginal opening in girls. \n\nSexual activity would usually puncture this membrane which leads to a bit of blood. BUT there are other activities (various sports, injuries, etc) that may puncture the membrane. In these cases, these females will not experience bleeding the first time they lose their virginity.\n\nHope that this helps! :)
