I also find it so interesting how it can vary from woman to woman, and from pregnancy to pregnancy!
So far with this one I haven't felt much of anything, other than being hungry constantly and needing to pee a lot. I am only 5w2d, though, so I know there is plenty of time for the yuckies to hit! I am fully expecting fatigue and nausea, I am just really hoping that it won't be bad!
With my first pregnancy, my boobs were SO sore for the first week or two. The day I hit 6 weeks, the nausea hit me like a truck. I was very sick through 13 weeks and lost 5-8 pounds.
With my second pregnancy, I had no breast tenderness whatsoever, but I was really tired and nauseous again.......but it hit me earlier (right at 5 weeks). But I also know my betas were really high (730 at 15dpo compared to 164 at 15dpo this time around), and I was taking progesterone which can make symptoms worse (I was very tired and pukey on those).
I would love to avoid the morning sickness this time, but I think chances are good that it will happen -- I just hope it holds off as long as possible so I can enjoy eating for a little while!
