I don't know about the provera, but I will share what my gyno said about ultra-light periods:
I went four years without AF, and finally had a (progesterone-induced) HEAVY AF in February. Then, I started birth control. Then, came March - pretty heavy again. Then April - and it was like yours. I wouldn't have known it was there if I hadn't checked the toilet paper. Nothing on the pads whatsoever. Barely there.
When I saw my gyno in April, I expressed my concern - I thought I was losing my AF again despite birth control - and she said that it takes 3-4 months to regulate on birth control. I don't know if this is true for Provera also, or not...but she said that, in an ideal world, women have light, barely there AFs, and so if I am having a "barely there" AF, to consider myself fortunate and not worry about it.
So, I didn't...until this month when I didn't get one at all. I'm without insurance, so I can't go back to my gyno and find out what's up.
So, my point - it may be nothing to worry about. If you're really concerned, put a call in to your gyno...but, if what my gyno said is right, getting an AF (even if it's ultra light) is all that matters.
I hope what I said made sense - if not, lemme know!
Cheers,
