I need to know if I could possibly be pregnant. I have a 15 yr. old son so I know how it felt when I was pregnant with him. I haven't missed a period and the pregnancy test have been negative, but I have all the symptoms... swollen breasts, nausea, headaches, cravings. And also, I have been having these flutterings that feel just like a baby kicking. If I am... I would estimate me being about 4 to 5 months. Is this possible?

It is possible to still get your period when you are pregnant, but I'm reasonably sure that the pregnancy test would come out positive, especially if you think that you are already 4 -5 months along. I'd go to the doctor with these concerns.
