How can you tell if you are pregnant without taking a PT? What if your PT is negative, but you feel you are pregnant?

Have you missed any of your regular periods yet ? HPT will not be effective till after you have missed the first period.
Also you are to use the first urine of the morning.

There is no other way to tell for sure, other than a PT. either at home or at your doctor or clinic

My cycles are irregular, so I don't know when my next period is going to be. I waited two weeks before I took the test and 6 weeks before I took it again. It came out negative, but I'm having pregnancy symptoms. I believe my pH is too low for the test to detect, but I guess I need to do a blood test or a quantitative test with numbers that tell you how pregnant you are if you are.
