I decided to buy a microscope that would be useful not only for fertility testing but my dd in a few years
On epinions, there were a few comments on how small the peep/view hole was, and for about the same price, I got this one that hooks into my computer (!!): (no affiliation)http://www.ink4inkjets.com/inplayqx3usb.html
Edit to add: I think it came within a week of ordering, I've been so busy that I don't exactly remember the amount of days.
I'm impressed with it, but haven't tried it for fertility (saliva) testing just yet. I should have some images to post within a week.
I read that it was 90% accurate, gave you a larger window of time (approx 48 hours) on when you were ovulating so that you wouldn't miss the window. It sounds good.
I'm curious to see if I'm actually ovulating, and when my days are (I am charting impaired).
