This is my first and I started wearing maternity pants around 13/14w
I haven't worn any at all with this pregnancy. I just bought bigger pants. Wore my regular shirts.
Yup I had to start at 9 weeks because my clothes stopped fitting even though I hadn't gained weight. I was showing by 13 weeks
With my first I only had maternity shirts and I didn't have to wear them until I was like 26 weeks. This time around I had to buy maternity pants at 12 weeks :/
With the second baby now, I started early as well, around week 11, maternity leggings, now i am on week 15, wearing maternity pants, comfy :)))
