2 weeks wisdom teeth post-op.. is this normal? do i have an infection? (photo)

it’s not shown in the pics quite well but i noticed that i can’t properly brush/clean my 2nd molars (teeth nearest surgical site) because my inner cheeks seem to be covering the lower side too much. im concerned because i used an interdental to reach those areas & saw faint red streaks on the brush (blood). is it probably just still swelling a bit at this point? was it sutured too tight? (sorry for the cavities, i'll try to get them filled when im fully healed from the wisdom teeth extraction)
