hi, i'm 17 years old and about a month ago, I lost my virginity, I have started to have quite a few symptoms of pregnancy but wasn't sure if I was just scaring myself and the symptoms are just because I have become sexually active? symptoms including; breast tenderness, sickness (usually in the mornings) nose bleeds, heavy discharge and not being able to sleep very well at night but feeling quite 'sluggish'... ??
