Well bed rest so far hasnt been too bad, we're on holidays in a hotel room so everything is close by anyway..
I've had some encouraging signs - some light cramping and lower back pain last night, and my uterus feels "sensitive" when I lie on my tummy like it did when I was pregnant with DS.
I had a faint but definitely there BFP this morning which is nice, and while I know its probably not even possible to get a positive this early, and its only the 9th day since my hcg shot so thats whats causing it, I still feel quietly confident that I am indeed pregnant..
Might be wishful thinking but thats ok!!
I guess time - and 20 more hpts over the next week - will tell!! 
Update: After hours of googling I am even more convinced that this is too early to be a true positive, but my lower back is feeling a little achy on and off so I'm still feeling pretty positive..
2nd Update: Another hpt, another positive. I'm hoping I never get a negative but they just keep getting stronger!! 
Oh and my hubby and I both agree this afternoon's test line is slightly darker than this morning!!
