After a MMC in April, my cycle has been all over the place. I have used the cheap Internet sticks but have never got a positive. I have invested in some of the CB ones as from what people have said on here they are easier to read. The instructions say to use in the morning, but I am sure I have read on here that they are more effective during the day?? Any advice would be very much appreciated. I need this month to be my month!!!
