I have these bites all over my legs popping up throughout the day. they're red super itchy. tried creams and they keep coming up. not any type of bug ?

Hives?: It these marks subside spontaneously in less than 24 hrs , they are likely hives. Else they may be something internal. Unless you live in a tropical swamp or a house full of flea infested pets, I greatly doubt that they are bug bites. If the bumps subside in less than 24 hrs , try oral antihistamine. If not, better to consult a dermatologist or allergist.
