Comments such as: "RIP that mans spine [sic]," and "You can see the struggle in his face" were the types of reactions to Tetteh's engagement shot.
But the bride-to-be responded saying: "Still confident... Your rubbish comments ain't ruining my happiness," and shared another picture of herself. She also thanked those who had posted positive comments: "Thanks to all for the compliments and best wishes... am honored."
Since the backlash, Tetteh has gained thousands of followers.
Her fiance, Amoah, told GhanaWeb he was proud of his partner.
"To me, I have always been a fan of plus size women and I am so proud of my woman and I don't care about what anybody says out there.
"In every society there are people who will try to discourage you from things that you seek to do but I am not bothered at all. And I don't regret posting those pictures on Facebook."
