A levels for sixth form

Just finished y11 exams, going into medicine as per the Asian genes (I do actually really enjoy bio and chem) Basically I’m continuing on to my school’s sixth form, and since I have high preds they’re pushing taking 4 A levels, and I really really want to use this to take an essay subject (HISTORY MY BELOVED the time periods they do at A level are so scrumptiousss) , but my parents are more inclined for me to take physics or FM (Initial options r bio chemistry maths) My sister’s also saying taking a humanity will make things a lot heavier than if I just took another STEM choice, which I guess I don’t mind. I was wondering if taking another STEM will be significantly beneficial in helping the subjects I need more or if I could maybe consider going for history.
