So I'm 19 and had unprotected sex with someone on the 15th February. I Came on around 27-29 january and it lasted till 5 febuary, i havent been on since. I have all the 'symptons' of being pregnant, but the tests I've done 4 tests, two say postive and two say negative. is it possible to be pregnant and the tests say negative? Am I pregnant?

Short answer is 'yes, it is possible to have a false negative' and any time you have intercourse there is a possibility of pregnancy. Birth Control reduces the chance but doesn't eliminate it. No birth control of any type increases the odds.

Long answer is that some women are into their fourth month before a pregnancy test will show a positive result.

To increase the odds of getting an accurate result, make certain you follow the directions on the test and take the test first thing in the morning after you wake up. That is the time period when the hormones are usually at their highest concentration.

Even though pregnancy is a major cause of late/missed periods it isn't the only one. Many women occasionally miss a period for no reason or due to stress, extreme weight loss, illness, etc. You can wait until your next period should be due and see if it comes or make an appointment with your doctor for a check up/pregnancy test and to discuss birth control options if you aren't pregnant/trying to conceive.

All my periods have always been regular, until that one time I've ever had unprotected sex. That's what's worrying me, and I can't get a appointment with the doctor till the start of next week /:

Next week is just fine. Until then, treat yourself as if you are pregnant. Get plenty of rest, eat a balanced diet, and avoid the toxic such as alcohol, drugs and tobacco.
