Five-months along, Abbey is gearing up for her second child with her husband of over three years, footballer Peter Crouch.
And despite telling fans she "couldn't be happier" to become a mum again, the 29-year-old has now admitted pregnancy isn't all it's cracked up to be.
Speaking to The Times, Abbey said: "One part of your brain is going, 'Oh my God, I'm so blessed, it's a miracle', and the other half is going, 'I can't bear this, I'm so fat, I'm ugly, I've got headaches, I've got spots, I feel sick..."
She then added: "Pete's not too happy with me moaning every two seconds [and] the perks... the big boobs and that - he can't go anywhere near because they're too painful!"
Already mum to three-year-old Sophia, Abbey knows all too well what to expect when it comes to childbirth and after a stress-free six-hour labour with her first baby, the model is hoping for a similar experience this time round.
"I had the most amazing birth [with Sophia]," she explained. "My mum thinks I was completely cheating. She and all my aunties were like, that's not real birth!"
However unlike her first pregnancy, Abbey revealed she and Peter haven't found out the sex of their unborn child and they won't until their little one's arrival.
Due to give birth in April, Abbey first confirmed she was expecting via Twitter in early December last year.
She tweeted: "Super excited to announce Pete and I are expecting our second baby! We couldn't be happier."
Since then, the former Strictly Come Dancing champ has been proudly showing off her baby bump in a series of selfies.
And although she may not be feeling her best, we think she still looks blooming fabulous!
