Weightloss after pregnancy?

Carlotta • Mama of three 💖💖💙
So I am 18 weeks pregnant and I know I have a ways to go before I should worry about this, however I want to know how much weight you lost after pregnancy, how long it took, and what steps you took. I am getting married 4 months after the baby is born and I want to feel comfortable on my wedding day and find a dress atleast a couple months in advance.
