What happens if you use more nose spray than directed and then accidentally ingest a little bit?

I'm really sick (and apparently retarded) and I've been sniffing nose spray all day to try to keep my nose clear, but it wasn't working very well so (dumbie me) I leaned my head back and put some in both of my nostrils, after a little I could feel it start to leak back to my throat and I swallowed some. I have a stomach ache now, idk if it's related, or if it might get worse? It's Afrin, active ingredient- Oxymetazoline hydrochloride.
