I am 16 years old. October 28th was the last day I had my period and I had protected sex November 10th and he did not cum. This was my first time I ever had sex. I still havent gotten my period and I took a pregnancy test and it came out negative. I've been having the urge to pee and cant, or feel like im not done when I do pee. My boobs are tender, I have been cramping, and Ive had mood swings but I usually have this anyways. My periods are very irregular and once I went 40 days late. im extremely stressed out about this and I need answers. Is this normal or am I pregnant? Please help.
