it is 2 days before my period, i have been urinating alot, have headaches off and on, bloating, constipation, and nausea. I went to the doctor today because I thought I was pregnant. He would not give me a blood test but took a regular pee test. He said I have a little blood in my urine and tested for infections, he said there were none. I asked him why I was peeing so much and he said probably because your constipated. When I found out I was pregnant with my first child I was horribly constipated and I dont usually have all these symptoms even when I do have constipation. Why did he not give me a blood test? And can I still be pregnant?
