Preg. test turned from negative to positive in less thab an hour. took another one and did the same. two different tests at two different times. thoughts?

Negative--repeat it: The hpts are quite accurate, but they have their limit--when you are too early the test may not be able to detect it. If you have 2 positive tests, the chance that it is truly positive is quite high. Not sure if you are trying to get pregnant, but I would say congratulations! Take your vitamins. Eat well; don't drink, smoke, or do drug. Consult doc! Good luck.
