I had my wisdom teeth taken out as well but not so brave, only one at a time. Last week my last one was out.
Normally it takes up to 3 weeks for the holes to close completely. The bottom holes are prone to getting infections I dont know why maybe gravity of food getting easier there.
I had an infection on the bottom side couple of years ago and formed a hollow cavity, usually that happens when people smoke but i dont smoke so just my luck.
Smoking largely affects healing process and people who smoke will more likely get an infection but I am sure your dentist would have told you that already.
I think you should wait and finish the end of your antibiotic course, with some antibiotics it takes up to two days to reach the active phase to start working.
Also in a lot of cases the dentist would have prescribed amoxicillin and clavulanic acid as the acid enhances amoxicillin effectivenes.
You should rince your mouth every our with salt water as that helped me, also rinse after every meal. Not too harshly but sort of take a sip of salt water and and move you head from side to side getting in all the places, if you do it harshly you might irritate the gum and it will bleed again.
To make salt solution I put one teaspoon of salt into a cup of water and mix.
I would still eat soft foods if I were you as well.
Hope this helps.
