In September, Chrissy Teigen and her husband John Legend lost a pregnancy, a boy they had named Jack, at 20 weeks.
Teigen has been public with her grief and struggles.
Earlier this month, Teigen was hospitalized for endometriosis surgery. It was the same week Jack was due.
"My little jack would have been born this week so I'm a bit off," she tweeted. "I truly feel kicks in my belly, but it's not phantom. I have surgery for endometriosis tomorrow…but the period feeling this month is exactly like baby kicks. sigh."
The 35-year-old model and cookbook author shared a body-positive message on her Instagram stories on Sunday.
"Happy Valentine's Day," she wrote. "Love yourself!! B**ch has been throuuugh it."
The message was over a photo of Teigen in the mirror covering her chest and showing scars from a recent endometriosis surgery around her hips.
