unusual cramping, bloating

I'm 17 and lately I've been having major abdominal cramping, nausea and bloating - usually these usually come with my period but there's no blood or anything. As well, I find myself going to the washroom very frequently - I've been to the bathroom five times already and it's only 4 in the afternoon. I've never had sex before so I know it's not pregnancy, can someone please tell me what's wrong with me?

I'm having those exact symptoms too! I haven't had sex either. I was wanting to know too.
