I'm 25 years old, my menstrual cycle haven't come yet, I'm 2 weeks late. I did a pregnancy yesterday from the store and it came out negative. I don't think I'm pregnant though because we use condoms, and me and my bf hardly have intercourse. Only once in a while. I think last week and 3 weeks ago. We use the condoms the right way. I really wonder why is late. I have a doctors appointment soon. I don't know what's wrong with my body, my breast are sensitive, I'm nauseous, my tommy feels bloated and it feels like if I was going to have the cycle but nothing.
