Can you use the ClearBlue Easy Fertility monitor as many times as you want?
Yes ma'am! It better be, especially for the price you pay for it.

You just have to buy the test strips. I got a pack of 30 for $25 on Amazon. If you have a regular cycle then it should last you around a month. You would typically use 10 tests per cycle. If you are irregular a pack of 30 might last you two months.
