This came of of me tonight and there was more in the toilet tissue. Can someone tell me what this is. My period did come but was a week late. I took a test before AF and it was negative. I felt very sick today. Nauseous and hot and the end if my work shift to the point where I had to put my head down. Also I have been have a terrible blatter issues and my urine smells pretty bad if I don't drowned my self with water ALL DAY. Just wondering if it's possible I could actually be pregnant or if it's related to the bladder issues I been having.
