I'd be wary of "Lovely@Melissa!xo". From a reliable source who's encouraged her to get in the habit of regular health testing, she remains curiously unwilling to take advantage of the NHS
For as much as it can be worth!
Honestly, if you are a foreigner displaying evident signs of either not having been here for long enough or showing that you might come from certain countries, the health checks provided by the NHS are worth not even the loss of time to pop over to the walk in centre. At the slightest sign where they feel you can't sue them, you should soon realise you are in the wrong place. Trust me, she surely gets better healthcare where she is from.
