Katrina - the waiting game in the process is so awful. You will find that you have really positive days were you are sure everything is going to plan and other freak out days when you are overwhelmed with fear that things haven't worked out. Your feelings are perfectly normal and are to be expected when the stakes are so high. As for the spotting, you could well be having some implantation bleeding which is a positive. As for the valarian, it may be best to check with the pharmacist. Good on your DH for being so supportive. I know it is so very very hard but try and take it easy for the next couple of days.
AFM - took Dr's advice for the morning and rested with legs elevated. He had also suggested for me to have caffine as a diurectic. Funny, as I haven't had caffine for the past 2 years. That said, I had quiet a few cups of caffinated green tea, which is a natural diuretic and limited my water intake and although still a tad swollen 'hey presto' much better today (thank goodnes). Have also lost 3 kgs since yesterday morning, which was clearly all fluid! For a moment I thought I was turning into Bert Newton!!
