Clothes fitting tight.

Destini • Mom of 4 with our last baby on the way, my main goal is a healthy pregnancy.
I am still wearing my regular clothes size 14-16. This week they are getting a bit tighter. I'm plus size, but I can't for the life of me remember when I needed to buy maternity clothes with my last pregnancies. I'm sure it was around now?? How about you? Are you wearing maternity clothes yet?
