Oh good luck 'JustMe.' Strictly speaking, I have about 6/7 days, but I am probably going to wait it out this month and not test too early - I haven't even bought any hpts! I am being really good this month (normally I test about 2 days po - only joking - 3 days po!). This is our first month ttc after the miscarriage in November, so I think I'll have to be really lucky to get a BFP this month. But, you never know...
Good luck everyone else trying to get a January BFP!
