Potty training

Mimi • 24👑 mommy to Jayden Isaiah 👶🏽💙 & V’Arie Skai 👶🏽💕

My son is 2 , 3 March 20th and he’s refusing to potty. Now he’s peed in the kids potty before but hasn’t since. I try to keep him in underwear sometimes and I’ll take him to potty every hour but he won’t use it but pees himself after. He screams when i get him to sit on the potty and cries when he sees underwear now and tells me he doesn’t want to put them on. He tells me sometimes he has to potty but never does it. What do i do ?
