When does the bloat end?

Madeline • I'm 26, husband is 31. We've been married 6 years and had our first baby 7/15/16 and are now due again 4/17/19
When does the bloating end and showing begin?! I'm 12 weeks and 3 days. I feel like I am showing but can't decide if it's really just bloat because my bloating was so horrendous! Thoughts? 😊
