I wouldn't consider either pregnancy hard. My first pregnancy was very uneventful and aside from mild heartburn, round ligament pains and tailbone movement restriction, I had no pregnancy discomforts at all. However, my son is special needs and this also fits him in RL as well. He has low muscle tone, severe global developmental delay and extremely complacent. He didn't move while I was pregnant at all so I'm not surprised that it was uneventful. However, I had an emcs so recovery was horrible, long and painful for me.
This pregnancy has been what I feel is typical. I had morning sickness from weeks 7 - 14, horrible fatigue throughout my pregnancy, aches and pains in my hips and lower back, heaviness in my uterus, pains from baby laying on/kicking both bladder and cervix, and all that, plus some other common pregnancy symptoms.. heart burn is starting to kick in now, too.
I'd have to say, both my pregnancies have been more emotionally draining with complications in my babies and being classed as high risk but have been really good to me physically with mild to moderate pregnancy symptoms. I have diabetes but I have most of the same symptoms pregnant on not when it's out of control so I don't contribute that to pregnancy.
I think every woman and every baby is a unique combination so expect all possible scenarios.
