Hello. Here is my product review of the ClearBlue Fertility Monitor and Test Sticks. I am now pregnant thanks to this monitors help and test strips! Thanks to She Speaks and Clearblue for the chance to try this and review. The ClearBlue Fertility Monitor was extremely easy to use. Yes, you must follow the instructions that come with it to get the best results. Keep in mind, this does NOT guarantee that you'll get pregnant using this monitor. All it does is help reduce the time it takes to get pregnant by telling you when your LH and Estrogen hormones peak right before ovulation. Conceived with only 4 fertile days in first cycle of use. Easy to use, simple and accurate. Got pregnant the first month using this fertility monitor. Definitely recommend it and will use it again. I would highly recommend it to those who have irregular cycles a very must have!! Of course lots of prayers too. Don't give up ladies, stick with the Cearblue Fertility Monitor. Don't wait, get one today-worth every penny.
