Those tests are impossible to resist, but wow, doesn't a negative test feel like such a downer? Even when you take it early?
Hope for this cycle: it takes 6-8 days after conception (NOT ovulation) for fertilized egg to implant. It can take even longer for that for HCG to register on a pregnancy test. Someone women don't test positive until well after their period is due! It's early days yet.
If it doesn't work: We're in this together, right? We'll think lots of positive thoughts and support each other for our next go-round. One thing I've been doing during this TWW is setting a totally unrelated goal for each of the days of waiting. It's awesome - I have actually gotten so much done and it keeps my mind off how convinced I am that it's not working!
