Is it doomed to failure if you're on your period and ?

Go to your doctor as soon as you can. Amenorrhea (stopping of menses) can be cause by physical or emotional stress. If you don't own enough body cooking oil you won't menstruate. Fat helps near the production of estrogen. If you're not menstruating your bones are also at risk. Your doctor will be able to lend a hand you determine what is causing this, later you will be able to treat it. Hope this help!!

Missing Period?

Oh YES - Stress can def cause you to miss your period. Other things could be: If you aren't eating properly or if you are underweight. I read somewhere that some of the girls on the olympic gymnastics squad stopped getting their periods because they didn't hold enough body lubricant! So, if you're very muscular that could be another purpose. But I agree with the other posters here who read out - go see a Doctor to be on the past the worst side in baggage its something else.

Why when I take a dookie, it looks similar to a long braid?

It could be stress. Do you run track, or are you anorexic, or just really skinny? If the answers to all those are "no", you should see your doctor. At lowest possible talk to the nurse first, and see if she's concerned.
