The first day of my last period is May 30 and it lasts for 6 days (June 6, 2011). Today is August 11, 2011 and no period at all. I took a HPT and resulted to NEGATIVE and after 3 days, I took another HPT and resulted (2 lines) but the 2nd line is fainted so I've decided to take a pregnancy blood test (serum) and resulted to NEGATIVE. I'm stating to worry now, I really don't know if I'm pregnant or I'm having a UTI. I have this symptoms (frequent urination, missed period, moody). Anyone can help me?
