Advance Maternal Age

So, I am 37.  I am not even sure what that means.  I don't know how to feel about that either.  I don't really care that I am 37, nor does it bother me that I will be 40 soon, so what.  I am happy with where I am in life and I don't feel any different, so why should getting older bother me???  But being pregnant and 37, that's a completely different ball game.  Apparently, every time I now have a doctor's appointment, I have to undergo all kinds of tests.  I am kind of happy about that, gives me a piece of mind, but what happened to one ultra sound at 20 weeks and a glucose test at 28?  So every appointment I get pocked and wait for some terrible news from the doctor's office.  At 12 weeks my doctor did a non invasive DNA test, which apparently can find baby's DNA in mommy's blood and tell you about all sorts of terrible genetic disorders.  Thank God, we didn't have any, but we did get to find out that Baby #4 is a Boy!  So, is it totally crazy of me to keep googling the accuracy of this test?  I just hate for everyone to be so excited, only to find out at an ultra sound that the test was inaccurate and its a girl.  I know I sound like a terrible person, so shoot me, but I have three girls!!!!!!!!!   The only person that knows what its like, is the person that has three or more girls, and if you are not that person, then don't judge.  My house is filled with tutus and all things pink.  I spend hours doing hair and getting them dressed and its only getting worse.  My husband does nothing.  He sits on a couch and says that if they were boys, he would help, otherwise he has no clue what to do with them.  I always wanted to have a little girl.  And when I had one, I wanted to have another one, because there is not greater joy then having a sister, trust me, I know.  But when our third one was a girl, well, that felt like we were sort of being cheated..... I mean, she is amazing and beautfiul and smart and we love her more than anything in the world, I feel like I have to say that for those that are judging, but its all true and she is the nicest one of the three, but why didn't we get to experience what its like to have a son.  I felt bad for my husband, who always waiting for the ultra sound tech to say, here it is, its a boy......So, this nervousness of mine makes sense.  I just want to make sure that this is not some sort of a practical joke and we are really having our fourth and final boy.  In any event, all these people that say, I just want a healthy baby, drive me nuts.  Of course we all want healthy babies!!!!!!  You do not need to say it out loud, we all know that!  And if something is God forbid wrong with the Baby you won't want him or her?  I just think that we are all people and its ok to be not politically correct and just come out and say it, I prefer to deliver a little monkey ;)
