pregnancy test flip flop - positive now negative ???

[Jem75]

At day 26 I had a very faint positive preg test, which was confirmed by my DR through a blood test on Wed. I would guess I am about 4 weeks - barely. My DR put me back on progesterone (100 MG) starting Wednesday night -- on Thursday I did two preg tests - one in the a.m. (digital kind, read "positive") and one in the evening that had the faintest barely there lines. Then this a.m.m (Friday) I did two more -- faintest pale line and now the digital test read NEGATIVE.

Does anyone have experience here? How can a test go positive back to negative? And does progesterone have anything to do with the readings? I am waiting for a call from the DR any time now with f/u blood test results - but this waiting is truly AGONIZING.

thanks for your advice

I done a clear blue digital test 4 days before my periods and it said pregnant 1-2 weeks I done it today on my due date of periods and it said not pregnant and I have start my periods. Do u think it's a false positive?
