The baby was less than 24 weeks old, so she could have legally got an abortion. In fact she was surprised when the baby was still born that she was as far along as nearly 24 weeks, which doesn't sound like she would have been panicking that she wouldn't have been able to have an abortion. She's contacted an abortion clinic to find out her options.
There's nothing in any of that to suggest that she would have tried to abort her baby illegally. I guess she may have said something that alarmed the HCPs but after a woman has given birth by herself to a dead baby unexpectedly I'm pretty sure she could be saying things in shock like "This is my fault, I wanted an abortion" etc. She would hardly be the first woman to blame herself for a miscarriage/stillbirth because she considered a miscarriage.
As someone with a medical condition where its quite normal to have 10+ miscarriages/late term losses, I find stories like these chilling.
