I am 17 and sexually active. Me and my boyfriend have not been using protection he he been pulling out. I was on the pill but I stopped taking it because I missed a few days. I had a uti and a yeast infection last week. And now I am 7 days late. I took a pregnancy test when I was 4 days late and it was negative but the test was a couple months old from were his sister had bought them. I have also been working 3 jobs and going to school one job being Geting up at 2 am to get my cousin and take herhome from work. Then come home and going back to sleep. I have been very stressed. So my question now is Could I be pregnate even tho the test was negative.
