I was just going to post a thread asking the same thing
I have been having heartburn for the past few days, and I was nauseous last night and much of today, along with the feeling of excess saliva which is so nasty. Ugh. My breasts feels somewhat fuller tonight and a little achy, but no real nipple tenderness yet. I feel more tired at night and like I am peeing more but maybe that is all in my head
The other thing is that my Crystal stick stops working - it's usually the first sign that I'm pregnant...
I am thrilled to be having symptoms so early, I will be 4 weeks tomorrow. After the m/c it helps to reassure me that things are progressing. I didn't really have a lot of symptoms with DS, some queasiness and tender breasts as well, but all that started around 7 weeks and didn't last too long.
