Usar ''If Clause'' com ''will'' ou ''be going to''?

I'd like to know if it's possible use an If Clause with (Be Going To) for example:
(What I've learned in school):

>> If it rains, I WILL stay home.

I wanna know if it's possible use this structure:

>> If it rains, I AM GOING TO stay home.

Thank you guys!
