I will do I am hoping they arrive in the next couple of days as I only a have a few of the expensive ones left and dont really want to buy anymore!!! Have no idea when I am going to ovulate this month as I had a mc last wed 23rd Feb I was 5 weeks pregnant and one week late for my a/f so who knows when I will be ovulating!! I tried using opks in the month of December (we were not trying in that month we had agreed to try in jan but just wanted to see what they were like!!) Anyway never got a positive on them they were a pack of cheap ones from the pound shop!!! So when Jan came I decided against using them and just checked my cervix and cm and managed to get pregnant! But decided to go back and try the opk this month as I have no idea when I will ovulate I hope they work! When are you due to ovulate
