I had a pregnancy blood test done and it came back negative.. Im 22 days late and my basil temp. is high.. The question I have is, could I be pregnant? The nurse at my doctors office said NO..

Blood tests aren't always 100% accurate, there's a lot of room for human error.

Wait until your next period is due. If you miss it, then try another test, either a urine test (at home, using first morning urine) or another blood test. If those tests come back negative, then ask your doctor what could be going on, since pregnancy has been out-ruled.

How late were you when the blood test was done ? Have you tried a urine test with the first urine of the morning
