You've came to the right place! Sooo many of us have been through this.... we're here for you! Try to relax and vent to us! That's what we're here for =o) Good luck to you and I hope the 28th brings a BFP!!!
The waiting is the absolute worst. This is easier said than done, but my advice is try to do as much as you can to distract yourself. Always have a book to read, start planning a trip somewhere so you can research all about that place, get a bunch of dvds of tv shows that you haven't seen or movies and just try to occupy your mind in any way you can so the time passes. Each night before you go to bed, tell yourself that one more day has passed. I don't think trying to read symptoms will really tell you anything because they can all be read one way or the other.
Good luck to you!
