I just saw this post and had to add that I too have not been one that has had to go to the toilet a lot either!! I'm just starting to go a bit more now, but that's largely due (I think) to the fact that I have started drinking more.

Up until 7w, I also did not feel PG at all. However, once I hit 7w, I certainly had the nausea hit home!! And I still don't have sore boobs, so there's another 'common' PG symptom that I haven't experienced!!

I'm glad that your u/s went well!!!
