What is your year-by-year GPA breakdown? Do you have a strongly rising GPA trend?
A few medical schools look at only your last 30-90 credits when considering GPA/sGPA.
Will you consider osteopathic medical schools?
Because of your very low sGPA, you will need a grade-enhancing post-bacc (formal or informal) followed by a SMP (Special Master’s Program) to have the best chance for a medical school admission. This means an additional 3-4 years of full time studies or the equivalent–without much in the way of financial aid except unsubsidized student loans. (Assuming you haven’t exhausted your student loan eligibility) SMPs are expensive–think $50K or more/year.
This is an extremely expensive road to follow without any guarantees of ever getting a med school admission (Probably 1 in 4 or lower). Also most successful SMP grads are admitted into osteopathic medical schools. If you will not consider DO programs, your road will be longer and with a lower likelihood of success.
This is not a route I would recommend to anyone unless medicine is only career they can envision themselves doing. I also suggest that you first consider other medicine-based careers first–PA, advanced practice nursing, anesthesia assistant, etc. --before pursuing a post-bacc + SMP.
BTW, the Georgetown program @crankyoldman linked above is for Career Changers—students without their science pre-reqs. What you need is a grade-enhancing post bacc, one that will improve your academic profile.

Choose “academic record enhancer” as the type. Choose “graduate” as the level to find SMPs.
Re: which exam to take. Many formal grade enhancing post-baccs do not require a MCAT or GRE score for admission. These are big money-makers for many colleges and they will accept most applicants.
SMP--aka Special Master's Programs-- the best of these are offered at medical schools and require a MCAT score plus the an application portfolio identical to what's required for a med school application--LORs, appropriate ECs, personal statement, etc. These program may offer linkages (guaranteed interviews at the associated med school) for the top-performing students.
SMPs are high risk-high reward option for student with academic issues. Basically you take the first 1 to 2 years of medical school coursework, often side-by-side with current medical students. You will be competing against them for grades. If you finish in the top 15-25% of your class, then you have about a 50-50 chance of getting a med school acceptance. If you finish outside of the top group, then you've permanently lost any chance at med school.
I would not recommend that you pursue a post bacc immediately after graduation. I would take a few years to work, distance yourself from your current poor grades and build up a financial cushion to help pay for any additional coursework you need.
After a couple of years out of college, you could take 1-2 upper level ( or graduate level) bio or chem classes to see how you do. If your new grades are good and you still have a passion to pursue medicine, then you need to take enough UL or grad bio classes (informal post-bacc) until you’ve raised your GPA/sGPA high enough (3.0-3.2, depending on the program) to be eligible for a SMP.
Unfortunately there is no quick fix for a poor GPA. It may take years to repair your GPA enough to competitive for med school.
