Im 18 years old and I have not had sex or even my first kiss yet, but my period is 4 or 5 days late and I am having weird pregnancy symptom's like tender breasts, back hurts (but more mid to upper back), morning sickness almost, more tired (but I do stay up late for hw but that's been going on for a couple months) and strange pains in my abdomen area I guess you would say. I had weird spotting today, but it was very very tiny and brown. I don't understand why this is happening and im pretty scared.
