I get them from ebay but others on here have gotten them from peeonastick.com or something like that. You use so many that i just get the cheaper ones.

I got the really expensive monitor and it worked well. I had borrowed it from a co-worker and have since given it back but it was easy to work and easy to read. Not sure that helps or if you've got that kinda dough.

I borrowed a friends expensive fertility monitor but returned it when I switched to IUI's and no longer need to keep track of such things on my own.

I really liked it! You set it for the cycle any day between CD1 to CD5 then it tells you to start peeing on a special stick that you insert into the monitor and as you get closer to ovulation it shows a small graph as to where you are in relation to ovulating.

My RE said to use First Response. I used it and it worked for me. I then tried CVS brand and it was terrible!!

i was really irritated with the OPK's at first. Though, i have stuck with them for the first time in a long while this month and the results are very clear with the clear blue easy (results window.) As a caution, read it right away and NOT after it dries cause then the lines look the same. Tonight, i thought i had to really pee and just trickled on it and got a positive... so the big O should occur any day. I will be curious how the results turn out the rest of the month. Good luck!

I have the Clear Blue Easy Digital OPK. It works really good. I got mine on ebay for alot cheeper then the stores, and it was brand new. I do buy the sticks at the store though and they are about another $50.00.

I used to use the Clear Blue Easy Digital monitor. I think I paid close to $200, and a box of sticks are $50 (they lasted me 3 months). I liked it because I didn't have to interpret what a faint blue line means.
