Emslie gave Fifa credit for recognising the development of the women's game. Popularity and intensity have soared in the past 10 years, with more than six million women and girls playing football in England alone.
At the time of the interview she was two months from the end of her contract with Angel City and had no news of a new deal.
Claire Emslie was still running at 81% of her maximum speed at 32 weeks pregnant, a mark she had not expected to reach.
Research set out in the account still treats that point as a loose recommended cut-off for full-contact football. In the second trimester the uterus grows over the pubic bone and gives the foetus less protection. Low-contact and modified training can continue if there is no medical reason to stop.
Whether to keep playing is, the account says, ultimately personal.
The fear that shaped older advice was miscarriage: a heart rate judged too high, a bad fall, or a mistimed kick to the abdomen. One player in the account said she had debunked myths she had heard about being pregnant.
Dufour said the body works hard in pregnancy and that aerobic capacity is pushed."The biggest stress test you're ever going to go through is pregnancy,"she said.
The same account lists pain, pelvic floor dysfunction, and motor control and movement among the main considerations for professional and amateur players weighing whether to keep playing and training.
Researchers cited there have identified what they call"clear cut"physical and mental health benefits for women who stay with football, including a lower injury risk after birth. One line of the piece puts it shortly: pregnancy could be a secret superpower.
The evidence those claims rest on is still thin. Up to 2021, only 6% of sports science research was done on women, and gaps are still being filled.
Like Emslie, another player has been documenting her training with her club's encouragement and said she was noticing more athletes doing the same.
For all the new positivity around the months before and after birth, Emslie said players still face hard truths, and that pregnancy is a sacrifice.
She did not want to announce the pregnancy until the second trimester. Until then, she told her teammates she was unwell.
Her own club, she said, was very supportive of the pregnancy and of her return. She made clear she was not speaking about that club when she said that, as a player,"you're wanted until you're not.".
