Tired all the time peeing all the time lower back and stomach pains while im on my period? - peeing a lot , stomach pains (lower stomach)

Me and my friend just started having sex, we had every day, until I start to trouble, and these strange symptoms. (its been so in recent weeks, first), we thought that she was pregnant, I started my period. (which a week ago and was not as hard as normal) but I'm always too late in tired.i middle of the night to go pee every 5 seconds, or at least have the desire to urinate d ', but if I do not usually pee much. Sometimes I feel like Im going to get sick and sometimes I, I get this really bad stomach pains just below my navel. and my average has pain in my lower back just like her great pain, but it hurts when I breathe ... im just really annoyed by all this pain. What is it?

I think it could be an in, but I'm sure you do not have one, before it was nothing like that.
