Hi I’d urge you to check the website of any medical schools that you are thinking of applying to ensure you will be completing all their prerequisites (and ensuring that any “equivalent” courses count). All medical schools have this on line now and it should be fairly easy to check out and take from there. Just a couple of examples http://www.uwmedicine.org/education/md-program/admissions/applicants/course-requirements
or say https://medicine.yale.edu/education/admissions/apply/premed.aspx. Also don’t forget you’ll need to do very well on the MCAT (hence many people take the sciences you mentioned). But as @T26e4 notes it is not required that you major necessarily in any particular field. Check it out directly from the schools you are considering and good luck
