opk help

[rawalter84]

I expect the big O on the 21st. I have been doing opks the last three days. They have been getting darker each day and was really close to positive today. So I did another one four hrs later and it was lighter! Could Ihave missed it? I do believe my urine was more diluted the second test. Has anyone else experiences this before?

How many times a day are you doing opks?

You should ideally do them at the same times, and with limited liquid intake for a couple of hours beforehand to make sure your urine is concentrated enough. If your urine was more dilute it would definitely give a lighter line. You definitely haven't missed it, your line isn't *that* close to positive yet.

From your pics, it doesn't look that much lighter so I wouldn't worry, I'd probably expect it to go positive tomorrow afternoon, maybe even the day after xxx

I was doing them only once a day around the same time but I threw in a second one. Thanks for replying. I was expecting a positive today so we'll see :)
