Hi, my name is Alexis. I am 18 and believe that I am pregnant. I am three days late on my period and have gotten two positive test, extremely solid lines, I took one at night and the other in the morning. I have not gotten any implantation bleeding but a recall about a week or two ago, I felt a short and quick pain in my lower abdomen. I am just curious to know if your opinion would say that most likely I am pregnant, or most likely another reason to these phenomenons.
