I have had 2 positive pregnancy tests and a negative at the doctor and now I'm on my period do this means that there is no baby?

You took home tests and they were positive but the test at the doctor was negative?

Which came first, doctor test or home tests? Did you do the home tests correctly?

My guess is you took the home test but you read it far beyond the time limit on the test.

Had you missed a period previously? When were all of the tests taken? As was asked, did you follow the directions carefully if you used home pregnancy tests?

Sometimes a later negative is due to misreading previous tests, sometimes it can be from an early loss.
