As we previously reported, Lohan was arrested twice in 2 days 2 weeks ago -- first, for allegedly bruising Major up in her Florida apartment ... second, for allegedly violating a protective order a day later, by trying to contact Major over the phone.

MiLo was charged today with 2 misdemeanors for the first arrest -- domestic violence and violation of a domestic injunction. And 2 for the second -- resisting arrest without violence (after allegedly trying to flee from police and falling into a tree) and violating a condition of pretrial release.
