Hun, I think they might delay AF, but will NOT give a false positive. Did your Dr say how long to use them for?

With me, I was already 6 w pg when I started using them, so that was not something I needed to worry about. It was my 4th pregnancy, the first three were very early miscarriages between 4-5 weeks (or chemical pregnancies)... And once I started bleeding at 6w with this one, my OB put me straight on the progesterone.

Hope it does the sticky trick for you.
