ic opk question

[CuppaSarah]

Bit of a daft question but I'm curious and google didn't give me an answer. Basically my opks have been nearly positive today. I've done three today as seeing such a good line makes me think the next one will be positive for sure.

I keep the last few days lined up on the bathroom side to compare. Anyway today's 3 opks were nearly positive, after I had a bath I glanced over and they're all now positive. Yesterdays are still negative though. Just wondering would the steam from the bath make them turn positive? I didn't look at the old ones before the bath so I can't tell if they were positive before. But they weren't positive at the half hour mark after testing.

I'm going to DTD just in case but anyone have any idea what to make of it?

They all vary, but you're not supposed to look at them after an allotted time at think. The ones I use say that you should only check the result at ten minutes! and not after.

Instead of lining them up, maybe you could take a picture on your phone and compare that way?

Today I threw them all out as it was driving me mad! These ones say up to half an hour for results. So I think I'll save myself the brainache and bin them after half an hour.
