Cheapy ovulation sticks

Amanda • I`m 24 literally married my best friend of almost 10 years May 9th 2015. He has 2 boys 6 and 2 we have been TTC our first baby since March2015. I thought this would be easy as pie, ha I sure was wrong
I have the clear blue smiley face ovulation kit, love it. But my last cycle was hay wire so i have no idea when ovulation will start i wanted to test daily but i dont want to use my kit because its expensive. Any suggestions on cheap effective ovulation sticks I can use until I start seeing some lines then ill use my kit to verify? And if so where can I buy them?
