Hi ladies, if you don't use OPK's as I don't, yet! Depending on how this cycle goes I may start taking them next month. I am now on CD7 and have started using FF this cycle to instead of OPK's I was just wondering basically if I DTD each night for the next 2 weeks or so, surely I couldn't miss ovulation, and as I won't know when for definite I ovulated, what CD would be best to take a HPT, although I am a POAS aholic, and even though I'm only on CD7 I've taken two already, BFN of course! Lol x
