Why did this begin to me?
Answers: It sounds like you may own broken your hymen. It's not always sensitive, so you might not have even notice when it happened. I'm athletic and my hymen broke sometime (probably during sports) back the first time I had sex. It's not unheard of given how athletic girls are at the moment.
its normal to spot but if it keep on happening parley to your mom or a close friend even call a doctors organization if you would liek but the same thign happen to me im also 15 You could have ruptured your hymen- it's impressively rare to break it during physical buzz [excluding sexual relationships], but it's probable.
The only passageway to know for sure is to take a look at it. Go to an OBGYN or your pediatrician and tell to them about it.
Linda:
You most likey tore a small piece of skin call the hymen. It is at the end of the vagina, closest to the perineum. It will bleed for a hours of daylight or two. Keep the area verbs and if you would like: soak contained by a tub of lukewarm water. It is a piece of skin that some claim "is proof that a girl is a virgin" and is regularly torn in a female's 1st sexual intercourse experience. Not a biggie. Stretching tore it. It will make well. Just keep it verbs and dry so it doesn't get infected & contained by a few days: you'll be just fine. Take concern! Dr Steve It could be nothing. Pay attention to it if this recur and how often--and tell your mom. Like I said, it could be only just that just stretching have caused for a time blood to come out, but if this happens more than lately that one time, then I really presume you should see a doctor...
