I'm 19 and I was suppose to start my period on the 17th of march and I haven't. After a week and no period I took a PG test at night before I went to bed and it said not. Then I waited till the morning took another one and it also said no. And now it's about 12 and I just took one it said no again. I have until the first to start if I don't. Am I pregnant? I had some spotting for not even a day this month. I just need to know what to do.

Three pregnancy tests say no. And from the sound of it, you used them in the period when they would be most accurate. For some reason, possibly anxiety over unprotected sex, your body is playing tricks on you and messing with your periods.

There's nothing to do, just wait for your period when it eventually comes.

Now if my period does not come for the month of March is there something wrong with me? I have never missed a period I mean they have been about a week late once before but nothing like this.

Probably not. There are all sorts of reasons for periods to play tricks, including the stress of wondering if you are pregnant. If there's anything else going on, keep an eye on it, but try not to obsess.

All sorts of other things can cause delayed periods changes in weight, diet, exercise, stress. If you're really worried, I'd call your doctor, but at this point, since the tests have been negative and you haven't mentioned any symptoms of anything to worry about, I wouldn't worry.
