The only thing this would do is extend my cycle by 2 days. It usually takes 2 days for AF to start once I stop the progesterone.
I've used progesterone cream in the past and it never extended my cycle, AF always came right on time.
I also used it during my second pregnancy, and I believe it is the reason I did not miscarry right away. As soon as I was sure that there was no chance my pregnancy would continue (I was getting blood tests that proved the numbers were going down), I stopped the progesterone and miscarried the next day.
So, I know just how powerful it can be. Of course, the fact that it takes 2 days to leave your system isn't surprising. We all react differently to these things.
If I were you, I think I would wait until I was positive I wasn't pregnant before stopping.
