What Causes Abdominal Cramps And Frequent Urination?

Hi there, I have symptoms which are, rapid hair and nail growth, dry skin, extreme stomach bloatation, lower abdominal cramp like pains , feeling sickly and faintish, feeling hot all the time and frequent need for urination. My last period was on the 5th till the 8th of September although it was on and off and pinkish at times. I haven t taken a pregnancy test yet as I am waiting to see if I come on my period which is due on the 6th of October. I ve never been pregnant but worried I may be. I have researched via the net but a lot of information is contradicting. Please can u advise me. Many thanks
