Is this kind of stomach flu normal? - is there a stomach virus going around january 2010

ok so ive left school for the sick, almost 4 days! And this does not seem normal at all. All these things come to me in a week, gradually or suddenly. OK to start Monday, I was 11th January orthapaedic some severe back pain. I do dance and acrobatics, and things circus. I was not sure if I'm still old, or had a serious problem. The doctor said it was something that because of the joints and muscles in the lower back and had to stay out of physical activity for 2 weeks after treatment, 3 times per week. bcuz I've sought, the dance competition of 4 weeks. anyway that night I was crying because my eyes to nausea and stomach complaints. I have done nothing Bad or vomiting had very bad pain. So I stayed away from school on the 12th, I did well because I vomiting after day. The next day I stayed home and I began again, but then I saw something different. I had my period, oh joy. im so against my back, my "stomach flu"?, and my time a bit difficult. nineteenth and earlyE 14 and 2 clock, my mother woke me and told me that I have a fever. I took Advil (Oh by the way, as I rest and sleep, and for the 2 nights that my mom gave me Tylenol PM that has helped a little, but I was back in 5 hours as this is the strange because in a Tylenol PM 13 years, you should really call.) anyway, and I took Advil and went back to sleep. I woke up this morning and I had to stay at home for the third day. tomorrrow I'll probably end up having to stay home, too. and I have an appointment with a doctor today. A few questions:
This kind of stomach virus that normal?
are the three things together?
i the second time was a very small amount of blood. Therefore, it has no ads in the early stages. It is something of concern?

I pray that it is long, but I need help. something feels wrong ... thanks:)
