This is my first time posting anything on this site. I am 17 years old. I have been living with my boyfriend for about a year. I have never been late on any of my menstrual cycles, but this time I am close to 1 month late. I get these kind of cramps in my lower abdomen area, as if my period was to come, but it doesn't. I have them close to everyday. I feel nauseous all of the time and my nipples are very tender and always hurt, but that also happens when I have my period. What exactly is wrong with me? Am I pregnant or just late?
