When girls have periods, does that mean that we loose more blood than guys or do we have more blood than them?

Men have a greater volume of blood flowing through their vascular system on average because they are larger than women.  However menstrual blood is the lining of the uterus that builds up over the course of a woman's monthly cycle and is not really comparable.  Besides, the amount of blood we lose each month is pretty minimal even though it seems like a lot.

Not necessarily. Among human females, the hymen is a membrane, part of the vulva, which partially occludes the entrance to the vagina and which is often physically torn when the woman first engages in sexual intercourse. Hymens vary in thickness, shape, and flexibility. So the amount of blood present will vary. Don't be embarrassed, let your guy know upfront that you are a virgin. That way neither of you are surprised if blood is present.

Yes, this is normal.  It's old blood left over from your last period that comes out right before the next period starts.  This shouldn't be anything to worry about.

That's normal - that is part of your period.  Remember it's not just blood coming out but also dead tissue from the lining of the uterus

The usual duration of the menstrual cycle is 3-5 days but flows as short as 1 day and as long as 8 days are considered to be within the normal healthy range. The average amount of blood is 30 ml but anything under 80 ml is still considered to be normal.  \nYou could get a measuring cup and measure out 80ml of water to get a better idea of how much blood 80ml is and to better compare that to what you are losing.

Some women do pass some blood and others do not...\nIt depends on the size of the girl and the vaginal opening...

I don't think it stops, I think it is simply that you've washed yourself and no blood is coming out... It's not as if you lose gallons of blood each time you have a period (although sometimes it seems that way!!) - it's not a constant flow!\n\nAs to what the other girl said - at night - you're lying down so unless you have a heavy period, the blood will sit inside you and wait for gravity to do it's thing when you're out of bed!! \n\nThese are my thoughts anyway... I'm not a doctor!!

yes, the less body fat you have in your body the less of a period you have. i am not a doctor so i would suggest consulting one on if this is ok or not.

Yes, its common.  Sometimes, when my period is done I bleed just a little bit.  Nothing to worry about.  It seems like it never wants to leave us. lol

No, in general menstrual blood color can vary from bright red to an almost black color. This is normal. You will usually find that your periods will start a lighter color (more reddish) and then turn brown or black for the remainder of your periods. However, if your whole period is a brown or black color I would go to a doctor just to check it out.

Most of the time, dark/blackish menstrual blood is simply what's known as "old blood."  The color depends on the rate at which the bleeding occurs; the slower the bleeding, the blacker in color the blood becomes.  Hope that helps!

maybe its the uterine lining. the menstrual blood is composed of partly blood and partly tissue. the uterus produces a lining and it gets thicker and thicker due to our hormones. if pregnancy does not occur, hormones drop, and the uterus sheds its lining during the menstrual period.\n\nbut for you to be sure, you should go to a gynecologist and check what really that is.

I started losing my periods when I exercised a lot I was running 10 kilometres 5 days a week I was eating like a horse. I would go to a doctor though just to confirm there is no other reason for the period loss.

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...

depends of your age.  if you are a teenager or younger, most likely nothing major, but if you are an older person, may relate to trauma, tumor, a bleeding disorder, medication that you are taking, or your anatomy is just make it easier to bleed.

Your birth control may be to strong for you. The brownish colored blood is usually defined as break through bleeding. Sometimes normal on BC when the birth control is too strong or not strong enough.  It's a good thing your going to the doc.

My gynecologist explains clots to me as follows: Blood is pushed out of your uterus when the uterus contracts (you don't necessarily feel these contractions, but when they are strong, you feel them as cramps). The uterus releases "anti-coagulants" during menstruation. These are supposed to keep the blood from clotting up as it passes from the uterus to the vagina, thus making the whole bleeding process easier.\n\nBut if you have days of heavy cramps and heavy bleeding, you may pass dark, chunky clots of blood. On such days your contractions are so fast and so strong that the blood gets forced out before the anti-coagulants have time to take effect. So the blood clots. And you pass big chunky gobs of stuff.\n\nIf the clots you are passing are larger than, say, a quarter, you might want to ask your doctor about it, because that indicates that your periods are quite heavy, and they might want to check for fibroids (benign tumors).
