Despite terminations being legal at a later stage, many hospitals do not have the facilities and moreover, doctors and nurses/midwives are able to refuse to perform them/be involved in them.
Source: used to work in gynae. There were only three out of nine consultants that would perform any termination at all, one would do until 12 weeks, one would do 14 and the other would do up to 18 weeks if and only if it was necessary to save the mother's life due to a medical condition where her other consultant(s) had said specifically that it was a medical necessity.
Everybody else had to either have the baby or try to get seen at a larger teaching hospital out of the area and hope that the wait for an appointment, wait for another dating scan and then the wait for a theatre slot didn't take them over the legal gestation limit.
As a result, in five years, only four later terminations were performed on patients who were initially referred to the particular Trust I worked at and they were all for saving the mothers life or because of severe fetal abnormality incompatible with life.
(I know this because, like the medical staff, the other PAs all refused to handle the paperwork, so it was all passed to me to deal with).
Got to love the legal right to religious exemption.
