I also am now a bit confused. I had ample posts last month, but now those posts are gone. I didn't note the number of posts that I had last month and they haven't done their contest thing yet. So, I have no idea what's going on......

Your posts are not gone. All are still visible if you check your own post history.

It was just the Monthly Posts count was reset from the beginning of this month.

At the time of this writing, your Monthly Posts count is 2 and Total Posts count is 53. So, you had made 51 posts before this month and all your posts, including the previous ones, are counted for calculating your total Credits.
