Absence of period / amenorrhea?

So i'm eighteen. not sexually active, and i havent had my periods since october of last year.

I went to my family doctor, and she got me to do a blood test and a pelvic ultrasound.

My blood test was normal, except for my liver which was off by a couple of numbers - which she said could be the result of hep b immunisations i just recieved.
Pelvic ultrasound was normal too.

Now she's referring me to the gynecologist. what other tests can i get to find out why im not menstruating?

Did they test for prolactin levels?

Are you eating a well balanced diet?

Are you a gymnast, ballet dancer or any other type of athlete?

Any of the above can cause amenorrhea.

I don't know, but you don't have amenhorrhea. Amenhorrea is when you're over 16 and have NEVER had your period.

Could be stress or changes in your weight. Other than that i dont know what it could be.

Norcalgirly, she does have amenhorrhea. What you are referring to is primary amenhorrhea.

Simplest is a therapeutic trial of hormonal therapy, first with a progestational agent alone, then with a combination of estrogen and progestin. That covers the vast majority of cases. Then simple hormonal assays (more directed blood tests) would be indicated. After that, it can sometimes get complicated, but those are a tiny minority.

You might have Polycystic Ovarian Syndrome. Don't panic. Just look at the list of symtpoms (http://www.womens-health.co.uk/pcos1.asp... and see if you have more than a couple. Because irregular periods are very common in young women, it could just be a matter of time before you regulate. There aren't many clear-cut answers to irregular periods.

alot of different things cause peaople to have problems with ther menstrual cycles. it is good that you are going to a gyno because they can fifure these things out, but minor things can also trigger periods from not coming and you may want to look into this. has your life syle changed in any way or form are you stressed because of a frightening situation that may have occured? Did you change your eating habits with vigorus exercise because alot of exercise with stop your periods in some individuals.Idon'y know anything about you but lets just say if you were anerxia starvation will promote this problem. The only other thing to do is not to get stressed out bythis because it will contribute to it as well. I hope you gewt some anwers from your gyno. good luck
