Anna also gave an insight into how her pregnancy is going when she replied to a fan who recounted their own experience.
"Fabulous. I remember that time, too small a bump for maternity clothes to feel warranted but too uncomfortable in your normal clothes too!! Hair band for the button and button hole and embrace the tight t-shirts! I also rubbed my belly all the time!!!!" the comment read, to which Anna replied, "That’s exactly me!!!"
Another follower also asked if she was expecting a boy or girl, to which Anna simply responded with a shrug emoji.
Anna and Tim, who found love on The Bachelor in 2013, announced they were expecting their first child back in May.
The couple made announcements from isolation via Instagram sharing a collage of photos of Tim and Anna posing with their ultrasound scan.
"It’s been so hard to keep this a secret, over the past few months, but I can now finally shout... I’M PREGNANT!!!" Anna wrote in her caption.
"With everything that’s going on in the world we feel incredibly lucky and grateful to be starting a family together, and we’re so looking forward to this next chapter in our lives. #BabyRobardsComingSoon"
Anna and Tim also celebrated their second wedding anniversary in June, marking their last one as a family of two.
The couple tied the knot in the picturesque Italian town of Puglia surrounded by friends and family where Anna wore a stunning custom-made Steven Khalil design.
On their milestone day, Anna shared a throwback photo from their wedding captioning it, "Happy wedding anniversary to my partner, my best friend and the love of my life @mrtimrobards. Cheers to our last wedding anniversary where it will be just the two of us. Soon to be, two becomes three."
