Do twin girls get their period at the same time?

This is such a coincidence! I was reading an article about Twins and I saw your question here... One of the story relates to your question, so here it goes...\n\nTwin coincidence? \n\nMe and My twin are both 13 and live in the UK. We have the same friends and have always been in the same class. We are identical an even close family members find it hard to tell us apart. We enjoy the same things and like the same food but still class ourselves as two unique people. Sometimes we completely agree and sometimes we disagree; we have our own views and feelings (for example I'm a lot more sensitive than my twin).\n\nOur story starts last May 2001. I woke up on a Tuesday morning for school, we have separate rooms and I'm always up first. Anyway I went into the bathroom and started up the shower but when I changed I noticed I'd started menstruating (started my periods). I was shocked and went to tell mum. Later that day at school I was sitting in my Spanish class (my sister doesn't take Spanish) and I got a message from the office saying my sister was upset and that she wouldn't say what was wrong. Apparently my sister had just started her periods too! It was on the exact same day which was really strange and on most months we menstruate at the same time :O) \n\n\nSo....... according to this story, it is quite possible, BUT I really don't think that it wouldn't happen to every twin on the planet! Because every girl is different physically and they go through different hormonal change!\n\nI hope this makes sense!

In these days, it's not really too early.  Girls younger than 10 get their periods, like at 7 or 8.  I'm not really sure why girls get it younger now, but it happens.  I got mine when I was 11. Which was in '93, so wasn't too back in the dinosaur age. *laughs* So I wouldn't be worried.

No, fraternal twins have DNA that is as similar as brother and sister would be.  That's essential what they are, brother and sister (or sisters, or brothers), but simply born at the same time, since it is two separate eggs being fertilized by two separate sperm.

Not usually.  Most women have 5 or so years of on-and-off periods with bleeding ranging from very light to very heavy to anything in-between.

Every girl has her own unique internal timetable. Most girls get their period from 9-16. During the year or so before menstruation starts, the physical changes that happen are underarm and pubic hair, a clear or yellow vaginal discharge, breast development, and even a growth spurt.

I have a friend who has quadruplets.\n\n3 girls and a boy.\n\nShe had AFI - and they implanted 3 eggs.  One egg split, creating idential twins.  There are 3 girls and 1 boy.  Two girls are identical, and the other two look different.

Ummm...every girl gets their period...well...most.  And from what I hear...it's not much to brag about.  They don't need to know...but if you really need to tell them...it's a pretty common thing...I don't see freak as being involved anywhere here.

it varies - depends mostly on how quickly your body matures.  Some have their period as young as 10 and others don't get one until they are sixteen or seventeen.

Okay, I'll bite.\n\nNo, it doesn't all come out at once, and it's not a steady stream either.  It's more like spurts.  Some days are heavy, some days are not.  You usually have a heavier flow during the first few days of menstruation, then it kind of tapers off.

yes.\npeople conceived as 1 of a set of twins, \n1 twin at the egg stage absorbs their twin.\nit's rare but yes it does & can happen.\nthey're born with 2 sets of dna.\ncarrying 1 type in their secreted fluids, but a different type in their marrow.

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

Congratulations!  No, you definitely do not have to worry. It's annoying when your period shows up unexpectedly like that, but not everyone has an ultra-predictable cycle, especially when they're really young.  It might take a while for your body to establish a schedule, but that alone is not something to worry about.

Just as some girls begin puberty earlier or later than others, the same applies to periods. Some girls may start menstruating as early as age 9 or 10, but others may not get their first period until later in their teens. The amount of time between a girl's periods is called her menstrual cycle (the cycle is counted from the start of one period to the start of the next). Some girls will find that their menstrual cycle lasts 28 days, whereas others might have a 24-day cycle, a 30-day cycle, or even a 35-day cycle.\nThe amount of time that a girl has her period also can vary. Some girls have periods that last just 2 or 3 days; other girls may have periods that last 7 days or longer. The menstrual flow — meaning how much blood comes out of the vagina — can vary widely from person to person, too. Some girls have such light blood flow that they wonder if they even have their period at all.\n\nOther girls may be concerned that they're losing too much blood. It can be a shock to see all that blood, but it's highly unlikely that a girl will lose too much: For most girls an entire period consists of anywhere from a few spoonfuls to less than 1/2 cup (118 milliliters) of blood — it just looks like a lot! It is possible for a girl to lose an excessive amount of blood during her period, but it's not at all common. (In some cases, a girl can bleed too much because she has a medical condition — such as von Willebrand disease.) The amount of blood a girl loses and how long her period lasts can differ from month to month.\n\nIf you're worried about your blood flow or whether your period is normal in other ways, talk to a doctor or nurse. Some changes in menstrual periods can be normal — but only a doctor can help determine the cause of irregular, heavy, painful periods, or no periods at all.

Yes. The twins share the same bloodstream, so what one twin gets into their blood the other will get also. There are documented cases of one twin having to take an aspirin for the other twin to feel the effects and vice verse. In other cases, both twins feel the effects. It really depends on how much of the blood and systems are shared by the twins. In your case, the other twin could also be affected by second-hand smoke inhalation.

Twin to twin transfusion is not to be confused with two babies sharing a placenta.  Identical twins share a placenta, and there are no health risks to mother or babies.\n\nTwin to twin transfusion is where instead of both twins sharing a placenta, one twin gets all the nutrients from the other twin.  It's a very serious condition, and if detected early enough in the pregnancy, women are often informed about abortion.  If it's not detected early enough, or if the mother doesn't wish to have an abortion, then the twin that gets the nutrition from the placenta may have a chance of survival.  The one who gets all the nutrition from its twin is likely malformed and underdeveloped, and is incredibly unlikely to survive at all.
