Ovulation tests

Any recommendations about which ones to use and where to buy? Have used clearblue digital but they are so expensive!!!

Now on to CD1 and gutted so looking forward to trying again this month- Im pretty much a newbie this time around although was a major addict when ttc number 1. Took us months then so hoping not as long this time. Just as obssessed and worried too even though i know its possible and adore my wee boy with all my heart!! I klnow i am lucky to have one!

cheers all!!
