For our first round of TTC (which resulted in DD) I first tried internet cheapies then reasonably cheap ones from the pharmacy. I found both too much hard work - too much analysis involved! LOL! I quickly switched to ClearBlue digital OPKs and found them fabulous and fool proof.

They aren't cheap in Australia though (about $70 for 7 tests) but I did manage to find a bulk buy on eBay for this pregnancy from the UK for a fraction of the price. I also charted with both pregnancies and thanks to regular cycles, I had a reasonably good idea of when I ovulate so there wasn't much wastage at all.

I love the smiley face you get on the digital screen when you're about to O. It's a great little incentive to get BDing! I'd highly recommend them.

HTH!
