What happens when the network diff falls below your mining diff

Has anyone ever had the network diff go below there mining diff when you set your diff. For example i am currently mining a coin which network diff was at 12k. So i set my mining diff to 10k. All is good finding blocks pretty regular, then the network diff drops down below my mining diff. Now during this period i do find blocks sometimes with an accepted share after the found block and sometimes not. if i catch it again i will take a screenshot

Now do i get credited with the block if it is below my pool diff and there is no accepted share after the find block. Has anyone else had this happen to them.

im guessing the no accept is because the share was less than 10k so it was not submitted.
