Clearblue Digital Advanced different result than Clearblue Digital
I used a clearblue digital advanced opk and went from low the last few nights to peak tonight. I was surprised so I used a regular clearblue digital opk about 15 minutes later and it was negative. I'm not sure what to believe. Also, is it ok to use the same monitor from the digital advanced from cycle to cycle or do I have to throw them away and use a new one each month?
