Does each pregnancy really get worse?

My first pregnancy was a dream. No sickness, no aches pains, I slept just fine. My second pregnancy was completely opposite. Morning sickness so bad I had to stop working, depression, very very low iron, aches, pains, heart burn so bad I would cry and it would wake me up in the middle of the night, and the 3rd trimester insomnia was HORRIBLE!! I also had to see a cardiologist because my resting heart rate stayed above 100. The good thing is both my labors were great! I even had my second child all natural without an epidural and she was born in 4 hours and I only pushed less than 10 minutes.

But I have always heard that with every pregnancy, it gets worse. I’ve also heard the third pregnancy and labor is really bad. Does anyone have any experience??
