Why did my snake regurgitate?

[Alfredo Pena]

It was fed on the 23rd and regurgitated on the 26th. I fed it again on the 30th and regurgitated the next day on the 31st. What do i do know. Do i feed it again or wait till next week to feed again. I did not handle it at all for two day s after it eats.
Its still a baby cornsnake so its in a 10 gallon tank
it has a 50watt heating light
aspen bedding
a log, fake leaves, and a branch for it to climb on
and a water bowl
you guys think any of that is upsetting it please tell me so i can remove it. And when would i feed it again. I dont want it to die so please help!
