Rude comments about my Pregnancy

Stephanie • Happily married. 💜 25 years young. Mommy to Maximilliano (7-9-16) and Maverick (10-3-18).
Okay So I posted a picture of my bump yesterday in my Facebook. The caption saying I swear to Jesus that wasn't there this morning #secondtrimester #babybump #wheredidthatcomefrom
I'm finally in my second trimester 14w2d and I haven't had a bump until now. And I was super excited to finally notice a tiny little bump. The picture was taken around 2am and I had just used the restroom not too long before. For dinner way earlier that night I had a salad. Well I woke up to a private message on Facebook from a friend of mine of 7+ years. She's pregnant with her second baby. 18-21 weeks along. And she messaged me saying this.
Your belly changes durning to day based on eating and bloating. Just remember that.
Like seriously!? Now maybe I was reading too much into it but I got upset. I felt like she was telling me my baby bump isn't the baby. Just bloating. Like it's not real yet. WHY in the world would you even make a comment like that? I felt like she was taking away from my moment, my experience. It kind of hurt my feelings.
Here's the picture I posted of my bump.
