The usual advice is to consolidate running 30 minutes for a few weeks before increasing time/distance, and then increasing by no more that 10 per cent of distance per week. It takes time for the bones, tendons etc to get used to the new demands of running, and doing too much too soon will indeed result in achoness at a minimum.
As our Rig says....your legs need to build up a does your stamina and strength.
Take some time to consolidate as Rig says, and enjoy some runs just for the sheer pleasure of running maybe... Shorter runs, new routes and some slow and gentle runs too ...all keeping you motivated and focused too
Brilliant that you have done 5 k, a great milestone.
Remember to build steady so maybe now consolidate the 30 mins for a couple of weeks then for one run a week add no more than 10% of your weekly distance! Go you, Runner HiddenGem
