My Adwords Ads went from getting 100 clicks a day, to 2-4

I'm not sure why. I limit my Google advertising to $10 a day per ad with a bid limit of $0.12/click and I used to get 100 clicks a day but lately I have been lucky to get 15.

I'm not sure if the position score has anything to do with it but it went from 7 to 10 on one ad and 8 to 9.6 on the other two.
