Good luck blueberry, get dtd! 
6dpo here... my creamy cm has now gone to clear/watery and there is more of it. Not sure if that is a sign of anything. Interestingly though I am pretty sure my cervix has risen and got softer (though only checking it for the last 3 weeks for the first time, I am not sure how accurate my assessment of that is!)
Interesting re the alcohol, there was a programme on radio 4 the other day and they were saying that the damage done by stress by women worrying over drinking and harming baby when they didnt know they were pg, is worse than the drinking itself! I have only had about 4 glasses of wine in total over my tww so far, maybe I should stay off the wine til af now
