Jane's labour had been difficult, lasting two days and three nights, probably because the baby was not well positioned. After the christening, it became clear that she was seriously ill. She died on 24 October 1537 at Hampton Court Palace. Within a few weeks, there were conflicting accounts of the cause of her death. More recently, various speculations have been made. According to King Edward's biographer Jennifer Loach, her death may have been due to an infection from a retained placenta. According to Alison Weir, she may have succumbed to puerperal fever following a bacterial infection contracted during the birth. Weir has also speculated, after medical consultation, that the cause of her death was a pulmonary embolism.
