Mum to beautiful Chloe, age 11. Mummy to an Angel, Faith, 02.10.10 HLHS. Forever missed.xxx
I have just finished using them for the 1st month and I tested during the evening. I tested between 7 and 9 - the times got slowly earlier (which I guessed would be ok as not going over 24hours). Sometimes I didn't quite get to 4 hours but as long as you've not drank lots of fluid earlier I found it fine. Although I was closer to 4 hours than 3 hours. Hope that helps!
