Blood test: Since you have irregular periods, it will be very difficult to tell for sure when you ovulated and when you will bleed.If you feel like you are pregnant I would suggest seeing your doctor to have a quantitative HCG blood test done which is much more accurate at detecting a pregnancy than the urine.It's possible you are having these symptoms without being pregnant as well but get checked to be sure.
