I started puberty when I was super young.  I noticed dark hair on legs and a very small amount of breast development when I was 10 years old.  I got an x ray recently and I stopped growing when I was 11.  Which is early for a boy or a girl.
Most of the people I see going through puberty in 2 ways.  Early or late.  If I started puberty so early then why does it still look like I am only just starting?  My younger brother was always a lot shorter than I am, he started puberty late, and now he is more than 6 inches taller and looks 3 years older.
I feel like the level of hormones that I have goes up and down.  Sometimes I really do look like I am actually going through puberty and getting older.  Sometimes my chest area gets somewhat larger and I start going through puberty more like a girl.  But then it actually just disappeared.  Two times I think my face might have started to look slightly male, but only just a little bit.  Hair has started to grow and then stopped growing and disappeared.  And then started growing again.  In one month I can look 2 years older and then the next month I look 3 years younger, literally.  It feels like I am going around in cycles instead of going in any certain direction.
I have gotten two hormone tests before for both testosterone and estrogen.  They were totally different.  The testosterone was way lower in my more recent one.  Which is almost 2 years later.  My doctor was confused because that usually that should not happen to anyone going through puberty, I don't think.  I also got FSH level tested and it was super high.
When I got a karyotype test it was XY.  Which was confusing for me because I have Atrial Septal Defect.  Which happens one in every 5,000 babies so it is very unlikely to be a coincidence that I also happen to have other development problems.  Atrial Septal Defect is a side effect of some genetic differences, like trisomies of chromosomes for example.  It could also be caused by some smaller DNA mutations.  Possibly with CAH 3 beta hydroxysteroid dehydrogenase deficiency?
Now my doctor wants to wait 6 months and take more blood tests, a third time, and then try to figure out the cause more.  My mom admits that it is happening I think but she does not talk about it.  She said lets work to be a boy, even with this problem.   My dad at least sounds like he is admitting it when he is talking about getting me testosterone and "chest fat" reduction surgery.  But then when I try to explain it is related to me being Transgender he completely changes, and says everything about me is normal.  He says I am 6 ft tall and look like any other boy my age.  Which is obviously not true.  I think I can easily stop from getting testosterone by making sure he does not feel comfortable admitting this is happening.
Both deeply care about me being a boy.  It is not because they logically decided against it.  It is because it emotionally matters to them.
I keep having abdominal pain for years.  I think I feel like it happens around the same time of the month.  It is different from being constipated, because that also happens all the time to me.  I also have had blood in urine three times.  It was just 100% blood.  There were also some small blood clots in it.  I think it was around the same time as the abdominal pain but that could easily be a coincidence.  It is at least worth mentioning because the whole thing is pretty unusual.
I also remember being in the hospital for something involving my private parts when I was a baby.  I once asked and it had to do with my intestines?  That does not make sense.  I was in the hospital a lot when I was a baby for a lot of reasons I don't know.  I was fainting for an unknown reason, and now I am again but have not been to the doctors office.  But whatever happened during that time I am sure my parents never were unsure at all that I am a 100% normal male.
I am constantly feeling really bad.  All I ever think about is being allowed to be a girl.  At school I am introducing myself as a girl.  And I tell anyone who knew me before I am transgender.  All of my teachers are fine with this.  And my parents do not know about this, I don't think anyone at school is going to tell my parents.  I make sure I wear certain clothing.  Most people think I look like a girl with shortish hair.  But I am very worried about getting a super short haircut.  Because then I couldn't possibly look like a girl.  This is making me feel a little bit better I guess.  But I am still just always waiting to be a girl at home and at school.
Do you have any ideas what could be causing me to develop like this?  And any ideas of what I should do in general?  Even if something randomly comes into your head in a week, it would help me.
