So AF was suppose to start today but hadent yet. Sometimes I go a day or 2 past my expected period before it arrives. Today I decided to take a chance by taking a test which turned out positive! However, I just recently started taking Thrive Le-vel to help with some weight loss which has made my pee a strong yellow. I was wondering if anyone had experienced a positive when taking Thrive and really wasn't pregnant. Or if my hubby and I are finally expecting. Ps. The test was taken a few hours ago and was showing positive, but now it seems to be getting lighter almost vanishing?
