Ooooh Coffee - sounds promising. According to my "What to Expect When You're Expecting" book, you can implant any day from 5 DPO onwards, and it typically takes a couple of days after that for you to produce enough hcg to show up on a hpt so it's definitely possible to get a BFP at 8dpo. I would try waiting a couple of days (easier said than done, I know) and then using a FRER.
Lucie - lovely to hear from you. Glad you had a good Christmas. Fx the more relaxed approach works for you and that 2015 brings you your BFP.
Sorry about the BFN Spinning - I really hope you have a naughty little bean that's decided to implant super late, but if not, I shall be keeping everything crossed that January is your month.
Victoria - I don't have anything to add other than
. Sending you a very big un-mumsnetty hug.
