So, I am 20 years old and have NEVER missed a period until this month. I haven't had a period since February 1st. My boyfriend and I use the 'pull out' method, and its always worked. Besides missing my period ive had some lower abdominal pain and back pain.. but that usually goes with my period. In the past week I have taken around 6 pregnancy test and they are all negative. I also went to the local urgent care yesterday and they gave me a urine test that came back negative as well. So, my question is could I still be pregnant? If I am, that's okay.. I just really want to know!!
