Does anyone else use the CB monitor? This is my 2nd cycle using it. Last month I got 2 bars (high fertility) for about 4 days then peaked for 3 days (CD 15,16 & 17) This cycle I only had high fertility for 1 day which was yesterday and today I peaked (CD 13) I also use ovulation strips as a back up since the monitor only allows you to test once in the morning. I been getting positive OPK strips since Tuesday night, the one in the pic is this morning with the same urine used for the monitor. I know the monitor is def positive does the strip look positive as well? Either way has this happened to anyone?
