Hi Doc, I am usaully very regular with my periods and I am now 5 days late. I went to see a doc and had a papsmear last Monday, I will get the results in 10 days. I have recently come off duromine, and I think I may have a UTI as I am experiencing soreness, stinging when going to the toilet. Do you think I am pregnant? Or does medication have an impact? UTI? Can that show a negative response? Please Help
