The best thing to do would be to try and put it out of your mind, stay away from this place, keep having sex regularly and just get on with your life. If you're anything like me the chance of that is zero. So there's a few things I do to try and stay grounded.
Get to know your cycle really well and note symptoms that you get at each DPO so next month when you get them again you know it's not because you are pregnant.
Implantation is usually between day 7 and 11DPO, with 9 being the most common. Before that any symptoms you get are a result of the normal rising progesterone and oestrogen and not pregnancy hormones. So for about the first 10 days of your tww just keep reminding yourself of that so really it's only a 4 day wait. I'm 8DPO with sore boobs and feel quite queasy, absolutely not getting excited about it.
Don't test before your period is due. Don't get sucked into squinting at indents and evaps, buying a million different kinds of test in case it makes a difference, it's the path to madness and there's only a few more days to wait. At 14DPO about 90% of pregnant women will get a clearly positive result. Just do one test then, or better still the next day if your period hasn't arrived, then you can move on. Don't have tests in the house. Go put the day your period is due and but 1 and 1 only.
Anyway that's my approach and so far I'm very calm and reasonable. This is likely to change if it takes a long time :) We're all afraid of being one of the unlucky ones but all we can do is keep trying. Good luck
