Hi, my name is Jessica. I am 18 years old, and a virgin . I haven t had any sexual experience whatsoever. I have a very steady period since I was 13. It always last the 4 days, and the symptoms are usual but very small. I was supposed to get my last period around a couple days ago, but haven t got it. I feel like I have my period, but there is no blood . I am a little nervous because this has never happened before. I researched this and the research said that is normal and could be stress related. I am under stress, but its the same amount of stress as the year and a half, and during that time I was fine.
