Moms, if you could name one thing you hate (or has challenged you so much) at each of the trimesters of your pregnancy, what would they be and why?

1st trimester: Morning sickness, coupled with my blood deficiency disorder I had to take a year off school (instead of 6 months) because I couldn't even get to the nearest shopping mall without getting dizzy :/ 2nd trimester: Nesting and preparing for my son because I started planning, budgeting and getting things prepared real early - I had everything we'll need from newborn to 3 months old ready by 28 weeks, and my stockpile of baby bath lasted 10 months. 3rd trimester: The sudden appearance of stretch marks from 32 weeks, started with 1 ... then 2 ... then one day, I woke up and thought my stomach got attacked by a bear. It challenged me because it took me 11 months after giving birth to be okay with looking at myself in the mirror :/
