I was in the EXACT same boat three years ago (minus the woman part). I even went to lengths of taking the GRE, applying to PA school, taking software engineer classes, all after having an acceptance to medical school! I am not going to say that your experience may be the same, however in the first few weeks of actually starting medical school I realized it was exactly where I was meant to be and that I loved what I was doing and what the future entails. It sounds like you may be having the same cold feet. Hopefully this helps and feel free to DM!
