Just that really.
With my first, the first trimester was hands down the most horrific time with the 24/7 nausea, and I found the rest of the pregnancy not too demanding.
However, I am now 32 weeks with my second and I feel awful. Not nausea but so uncomfortable, exhausted, bloated, can't sleep, achey - just everything!! Much harder than the first trimester this time.
Which one did you find harder?
