nasal spray?

Amanda • I`m 28 years old. Married since 2011. We have a 5 year old son. Baby #2 due in nov2016!
Anyone know if nasal spray, medicated, is ok during pregnancy? Trying to clear a very clogged ear with a Neti pot but it's telling me to use medicated nasal spray. It's been clogged for 4 weeks, I've gone through 2 rounds of antibiotics and it's just stuck behind my ear drum. I'm desperate at this point. I'm 39w.
