What cycle day should I start with the opks? And do I need to do it them same time every day or does it not matter?

What cycle day should I start with the opks? Are your cycles 30 days? If so, I would get the cheap wondfo brand and start testing around cd8 just in case. I had 24 day cycles and usually o'ed around cd8 so I started testing around cd5-6. And do I need to do it them same time every day or does it not matter? It does not matter but I would not use FMU and if your line starts getting dark test twice a day so you don't miss it.

I'd agree that cd8 is a good starting point. I usually go by the CM too!

Once it's watery then I would start to test....

I agree, depending on how long your cycle is. I have a 32(ish) day cycle and O around CD 17, so I don't start OPK testing until CD 13 or so. I but I agree, if you are having watery cm then start testing!
