Potty training 😩😩😩😩😭

So I'm about to give up! My almost 2 1/2 year old has been in underwear and doing good for about a month and a half now. All
Of a sudden the last two weeks have been horrible! He'll have accidents all the time especially #2. He'll have at least one accident at day care and then come home and just stare at me and pee.Β 
I'm honestly at a loss and don't know what to do! Is there such a thing as regression and how do you handle it or is he just not ready?
