I'm feeling pretty good so far. My PMS is enough to contend with and this seems a lot easier to deal with -- just feeling a little queasy (almost barely) and then there are I guess some light cramps. My breasts are a little fuller but you would have to be intimate with them to notice, they actually hurt less than they did last week when I was PMS-ing.

Honestly for those of you who haven't been pg before it isn't earth shattering necessarily (which in my head it always seemed like it was). It is like a natural progression of the menstrual cycle which I usually describe as being a test cycle each month to help things tuned up and ready to go.
