Using otrivin while pregnant?

I woke up with a sinus cold thursday morning, it's saturday afternoon, and my nose has been very stuffy and then running like crazy. I've took tylenol a couple times just when my head feels so congested like its going to explode and i asked the pharmacist what i could take and she said otrivin. so i've been using that, probably only 3 times now, I just do one spray in both nostrils and only when i feel i need it. i'm 20 weeks pregnant and been reading up on it to make sure it is safe for my baby and everyone seems to say its safe. has anyone else used it while pregnant? I just don't want to drive 30 mins to check with my doctor that it is ok. I plan on throwing it out in a couple days since the pharamcist said to use it for 4 days.
