Negative test, periods, protection?

Hi I really need help because im stressing. I had protected sex about 20 -21 weeks ago, my periods have continued though they are irregular anyway they have started to get shorter these last couple of months around 3-4 days and have been 7-10 days early. I'm only 14 and I know its way to soon and i'll never ever do it again till married. I took 2 tests both negative one when I would of been 16 weeks and one when I would of been 20 weeks also I still have ovulation discharge (I think) and craps 10 days - 2 weeks after period also been stressing a lot.
