“​​The last few years have been a blur of emotions to say the least, but joy has filled our home and hearts again,” she captioned the snaps. “1 billion shots later (in the leg lately, as u can see!) we have another on the way.”

Teigen admitted that she had fears about the pregnancy after the loss of her third child, Jack, in September 2020.

“Every appointment I’ve said to myself, ‘ok if it’s healthy today I’ll announce’ but then I breathe a sigh of relief to hear a heartbeat and decide I’m just too nervous still,” she added.

“I don’t think I’ll ever walk out of an appointment with more excitement than nerves but so far, everything is perfect and beautiful and I’m feeling hopeful and amazing. Ok phew it’s been very hard keeping this in for so long!”
