When I first got my period, I had the first one, and then didn't have another for 5 months! But i'm tiny, and I was just starting out.

Because you've been regular for so long, I think that you should probably go see a doctor just in case. There's probably nothing wrong with you; nature is just giving you a respite! But there's no need to let something like this haunt you, when a simple doctor's visit can make you feel content again.

Thanks. I guess you're right, its better to see a doctor and be over and done with it than to be haunted and worried by this all the time.

This is a condition that should cause you concern to go to the doctor. Your hormones are probably not normal and you're most likely not ovulating. You should try to fix this before you try to have kids.

I have other type of hormonal related problems and like you, I dont exercise much. I think lack of exercise does cause our hormones to go haywire. Recently I started taking high potency vitamin b complex and it has brought my period back to normal, as in 30 day cycles with 5 day period instead of 50 days cycle with 10 day period for me.

Try taking vit b complex, one a day woman and calcium.
Good luck.

Maybe u have pcos (polycystic ovarian syndrome)--it might not be serious, but the doc might tell u to get on birth control to regulate periods... A lot of women have this, especially young women 15 to 25, it's very common... U'll get an ultrasound, check for thyroid problems, etc.

Im 17 years old and i came off the pill 7 months ago. Iv had 2 periods since comeing off the pill and my last period was in Feb, iv been sexualy active with my new partner since January! I havent had a period in 13 weeks now. Iv done a few home pregnancy test which have all come back negative iv been to the doctors and had a urine test which also came back negative. Iv been to have blood tests done which also came back negative and said there were no problems. Iv got no signs of being pregnant although i feel iv put weight on but nothing is notisable. I did have unprotected sex 3 weeks ago thinking that i couldnt get pregnant cause i havent been having periods. Doctors have told me to wait another 2 weeks and do another home pregnancy test, but i still have no signs and im wondering what could be wrong with me?
