Hi everyone! I have never used OPK's before but thought I will give it a go next month because I am going to do everything different to what I normally do. So fingers crossed over the next few months that I get my BFP.

Anyway, I have read that most people buy them off ebay. Can anyone tell me roughly how many I should buy? Do they come in a pack (like the ones i have seen at the pharmacy) and roughly how much should I be paying?

Thanks for your help girls and good luck to all of you.
