A little bit of nausea for me too, here and there. Nothing too much really, but enough to make me think "hmm, I feel a bit off". I think my sense of smell has increased a little too, especially when it come to food smells.
Sam - yes it was amazing to see the 3+! I debated about whether or not to do it this morning as I'm only just 5 weeks and I didn't want to be disappointed if it still said 2-3. On the other hand, I knew that if it did say 3+ I'd be super happy BECAUSE I'm only just 5 weeks, so my hCG must be on the higher side. Let me know when you get yours!!
