4cats, so sorry to hear about Leicester. Liverpool could still be good news, but if not, remember that most applicants do not get offers first time so she is in good company!
For DS, time has been a great healer and he has started to feel positive about a gap year, has several things which he would like to do which will mean he gets real benefit from the year as well as having the chance to grow up a bit. I think that maybe the people who have had paid jobs and lived in the "real world" have an advantage over him in interviews.
If your DD does not get an offer from Liverpool and really wants to start in 2019, from my research there are still a lot of options.
UCAS Extra - Still showing Lancaster (but that is BMAT) and Nottingham, Lincoln pathway. Maybe more will come up later, I don't know
Clearing - St George's, London has a policy of keeping places for really good candidates they might pick up around results day. There may be others, if there are any that DD is interested in, she could contact them and find out what their policy is if they have vacancies on results day.
Waiting lists - Getting student numbers right is a fine balancing act and they don't know which "firm" offer holders will get the grades and which "insurance" offer holders will take up their places, so on results day there is a lot of movement. Some med schools only like to take people they have already interviewed and did not score highly enough for an offer, but they only keep applicants who have no offers on waiting/reserve list. Others (such as Newcastle) will not re-consider applicants in a cycle in which they have rejected them. Leeds notify people in May if they are on the reserve list. Sheffield have already notified people who have Reserve places, but several of them (including Mimiasovitch and Weaverspin DDs have other offers), so it may be that they allow more people onto the reserve list once people have chosen firm and insurance choices if they don't have enough left. It is worth finding out what the policies are of the ones where your DD has had interviews.
One thing which is definitely worth bearing in mind is that it is very difficult to get through on results day to the med schools which have vacancies, so if that is the way your DD wants to go (if Liverpool does not work out) she should get together a list of the med schools she is interested in and their phone numbers before results day to maximise her chance of managing to communicate with them.
Fingers crossed for Liverpool, but hope that your DD adjusts to it as well as my DS did if she does not get any offers.
