Query: Worth a shot

Well, I'm not sure if this did the trick or I am just super fertile, all I know is I got pregnant the first round of using this monitor. Although my husband and I weren't "trying" for very long before trying the monitor, in my eagerness to be a mama I started using this after 3 months of trying and became pregnant on the first round. A bonus is that it was used by at least 4 other moms before me, so it seems to have a good lifespan. A friend of a friend purchased it online, used after spending at least a year trying without success. After using this for a few months she got pregnant and it was passed down several times until I inherited it. Now I am passing it to my friend in hopes that it will help her speed up the product. It's worth a shot!
