Current research indicates it's not a BF problem, but a caloric problem. Check your burn/eat numbers.
If you are really serious there are some very rare "disorders" that would not have you being able to get pregnant. One very strange one is where the person is actually male- yx, but because his cells cannot respond to testosterone in the womb, he never changes his development to become a male. So he is born "female". At that a very attractive female as throughout his development there is little influences by testosterone to make his body more masculine looking. (every persons bodies make use of both male and female sex hormones in development) I'm not certain but I vaguely remember this strange condition was discovered because the "women" involved could not have children. Needless to say one episode of "house" has already incorporated such a rare condition.
All humans are female until hormones turn them male, the opposite is true of other species. That is why there is a fuss about estrogen mimickers in the environment, and parent might be willing to get organic" food for their daughters, but not fuss much about their grown sons. These estrogen mimickers can be stored in body fat. That can be a problem if it is released into the bloodstream during pregnancy. It may interfere with a foetus's male development.
Also it is true that those who start their periods early, end late; and those who start their periods late, end early. So if you are interested in having children, and there is nothing "wrong" with you, you should still find out, because you may have to plan for ending motherhood earlier compared to your sisters who will have a longer time to have their own children. I read somewhere some women who start late may end by 35 years of age. Thats a lot shorter than the average of 45 to 55 years. They can bear children for less than 20 years? You might as well start figuring out now what might cause problems for your plan of having children sometime.
There's another condition called poly-cystic ovarian syndrome (PCOS), which is where your body starts to prepare to ovulate, but the eggs never quite make it and instead stay in the ovary and form little cysts (not the big painful kind.) I have a minor case of this, and have had very irregular periods in my life. I had my first when I was 14, then not another for a whole year later! And there have been various other times in my life when I've not had a period for a long stretch of time, like a year.
Anyways, my point is that I saw a gyno about it and they put me on birth control, which actually helped kick my hormones into gear a little. Even after coming off b.c., my cycles were quite regular for a long while, although they slowly started get a bit irregular again--but still not nearly as bad as before.
Of course, being on b.c. gave me a blood clot in the deep vein of my leg! Very dangerous! Turns out I have a blood clotting disorder, which I never knew about before that. So, a word to the wise--make sure you have no family history of blood clots before you get on hormonal birth control!! But sorry, I digress...
Gaining a little bit of weight might help you too--it's worth a shot, at least.
hi there katergater - i am right there with you, i never naturally get my cycle.
this is what happened to me - i got my period when i was pretty young, probably 6th-7th grade? then as a freshman in HS i succumbed to anorexia and went from a healthy 125lbs (aprox?) to 100 lbs in no time at all. (and while being an active athlete)
the consequences? no period. and for me, my cycle was always heavy and lasted 6 days. so what a surprise that was! i made the mistake of living it up and enjoying the freedom until my mom realized i had not asked her to buy any feminine products in over a year. so off to the gynocologist i went, as a sophomore in HS - fun times. and mind you, by this time i had gained all the weight back - and was back at 125lbs.
my doctor explained it to me in a simple way -
1) i has slowly started killing myself by not eating when i had the ED, so my body decided to shut down my cycle - it wasnt necessary to have and it needed to hold onto everything to keep the rest of "alive" (losing a cycle is usually the first sign that you are on the road to doing serious damage to your body)
2) - my hormone levels were out of whack and i had more testosterone than i had estrogen. odd, right?
3) my mom also had ovarian cancer, so my doctor looked into that too - no cysts.
the solution: she put me on birth control to help me get my cycle back. i was on it for almost 4 years (until summer between freshman and sophomore year of college) and then i started getting sick from it - migraines, nauseau. my doctor suggested i try to come off of it for the summer and see if my cycle comes back. so i did and did it come back? nope. so back on it i am... currently at the second set of 4 yrs on the pill. a long time to be on birth control.
the long term consequences - i will probably never naturally get my cycle and having kids will be a challenge. she briefly mentioned gene therapy to me in my last visit --- and since i am not at that stage in my life, i decided not to dig deeper for info since i dont need to worry myself sick over pregnancy when that is quite a few years away.
it is not impossible to have children without a natural cycle, just more difficult. im sorry you are going through this, it is not fun at all and i can only imagine how frustrating it will become when we get to the age and point in our lives where we decide to start a family. i am hoping for both of our sakes we have supportive families and husbands!
Hi again Katergater--sorry I forgot to check on this thread after I posted--now maybe it's so late that you'll never go back and read this...but for what it's worth, I thought I'd answer your question. Having PCOS can make it difficult to have children, but not impossible. I myself have sort of normal periods now, after having been on the pill and then getting off. So for me personally it's less of a big deal than for some women with full-blown PCOS. I have a good friend who has PCOS who tried for like 4 or 5 years to get pregnant, and never could. Then, she decided to try glucophage, which is supposed to help regulate your insulin, I think (PCOS is related to insulin resistance in some complicated way.) And then like a month after she started taking it--voila! She conceived! She now has two little boys, and I think they are still planning to have more kids.
So the point is, no PCOS does not automatically mean you can't have kids naturally. There are some treatments to try (some people find success just eating low-carb for a while, I've heard) that can help things, so if you *do* end up having PCOS, don't despair! I know there is at least one website support group for women with PCOS, which I have browsed around on a little but not joined--you could find lots of advice/ideas there or on a similar one--just google PCOS.
Of course, you might not actually have PCOS! The first step would, of course, be to talk to your doctor about being tested. (For me, they did an ultrasound of my ovaries to check for cysts--there might be other tests too, I'm not sure.)
Best of luck to you! I know it's tough to have to go through.
