Should I see a doctor?

(I know, my avatar and name are male. But never mind that.)

I am eighteen years old and biologically female. I first got my period when I was twelve, and while it has never been a regular monthly occurrance, (usually it was five days on, five to seven weeks off) it has been very irregular recently.

The last time I had a period was in the third week of June, and there's no sign of it happening any time soon. Before that, my last period was in February. I know that two periods a year is not healthy. There is no way that I could have an STD or an infection that would be causing this, and I don't exhibit any of the other symptoms for PCOS, which is the next closest possible cause.

I am a female-to-male transsexual, but I have never taken hormones or had surgery of any sort, so it's not as though testosterone would be the problem. As an FTM, I don't want to menstruate, and I don't want to take estrogen to cause menstuation, but I am worried that the amenorrhea signals a problem.

Help?

If you have been working on building up your muscles more recently this could have an effect.

Do speak with your Dr. Also discuss with him/her about getting testosterone injections. A Psychiatrist with GID specialty may need to authorise this though.

yes you should see a doctor

I really think you need to go see a doctor and find out what is going on and what you can do about it. this type of problem can't be good.

yes, you do need see your doctor.

Thee are a number of possible reasons why you're not menstruating, and many of them are not serious; but some are, so you really DO need to see your doctor.

Do you have very low body fat? The reason I ask is that I used to be very athletic and there came a point where I dipped to 15% body fat. At that point my periods started going away. I got concerned and saw my doctor about it. He informed me that in general, a female needs to maintain at least 20% body fat to have a normal healthy menstrual cycle. The reason being that if she gets pregnant, she will need those fat stores to sustain her pregnancy and to produce a healthy baby. It would make no sense to continue being fertile if the body has no possible way of maintaining a pregnancy to full term.

Even if you do have low body fat, it is still a very good idea to get checked out by a doctor just in case!
