Hello ladies, I'm TTC DC3, was so lucky to conceive first 2 straight away. This time, I'm trying out a CBFM - just out of curiousity really - but just got a BFN on my 4th cycle. I think the bottom line is we're not having enough sex - we've never managed to DTD on both peak days, we (well, mainly DH to be honest) runs out of steam by that point in the month. How are other CBFM users getting on?
