Like a period so I went bought another one and it still saying positive this is my sixth pregnancy and never experienced this

You're probably having an REALLY early miscarriage. What had probably happened is that you got an egg fertilized but there was something severely wrong with the developing embryo and it was not longer viable, so in response your body is removing it in the same fashion that it sheds your lining every month. The reason that you're still getting positive tests is that you're body is still produce and eliminating the hormones that the tests are made for and it probably will for the next little bit.

I would take this time to go to and talk with your doctor to make sure that everything is okay with you. Early misscarriages like this aren't usually a big deal, but there is always a chance of things going sideways.

Good luck.
