"After a year of trying to conceive I bought the CB Fertility Monitor, I got pregnant at my first cycle using it and had a son. I then used it again when we were trying for number 2 – I got pregnant on the 2nd cycle and had my daughter in May! Thank you Clearblue – best money I ever spent!"
"I just wanted to say, that I think this product is amazing, I used it after struggling to conceive for 4 years. I am now using it again to help with conceiving baby no:2. thank you so much."
"I just wanted to write a note to say a great big thank you. I purchased the Clearblue fertility monitor and test sticks in November 2011 ahead of my next cycle in December 2011. I've found out I'm pregnant and over the moon. Thank you so much for all the wonderful products you create, we were so lucky for the monitor to work first time for us and after 3 months of trying this was the perfect product for us and I would highly recommend it to anyone. Our baby is due on 10th September 2012 and it's all thanks to Clearblue. Thank you for providing a great service."
"I am very satisfied of using the Clearblue product. I must say that I was trying to be pregnant normally for 9 months with no results. After the 9 months passed it came from my mind to continue my efforts by making IVF. At the same moment I was informed from an internet site about Clearblue Fertility monitor and it looked very interesting so I decided to give a last chance to a normal pregnancy than an IVF. I ordered it through a foreign internet site, because I couldn’t find it in Greece. I used it and followed its results and I am very happy to announce to you that at this moment I am 10 weeks pregnant and I informed most of my friends how helpful and simple were to use this product and also that it worth the money!"
"I tried everything and I think that Clearblue fertility monitor is a very smart product and I think that it will help and other women as it helped me."
I bought a CBFM and we got pregnant the 1st attempt :-) My cycles are not your typical 28 days, they vary from 32 - 35 so my husband and I didn't really know when I was ovulating. The CBFM worked wonders - thank you ! I also bought the CB PLUS tests and they showed positive 2-4 days before my period was due. Roll on April for our little bundle of joy to arrive !! Thank you :-)

Frequently asked questions
Is Clearblue Fertility Monitor suitable for me?
How accurate is the Clearblue Fertility Monitor?

Can I use Clearblue Fertility Monitor Test Sticks from different packs?
How do I use the Clearblue Fertility Monitor if I work night shifts or travel between time zones?
Ideally you should set your ‘m’ Button so that your Testing Window permits you to test using your first urine after waking, which may be in the afternoon. If your sleeping pattern changes temporarily during your testing period, you should collect a sample of your first urine upon waking. You should store the collected urine and check your Fertility Monitor during your next Testing Window and, if you need to do a test, use the collected urine. (Refer to question 17 in the full instructions for use on testing with collected urine.) Download an instruction booklet here.
