Can't breath

Dulce
Had a very bad cold when I was 16 weeks, currently 22 and ever since that cold I have had a stuffy nose every day and I need to have my nasal decongestant spray or I won't be able to breath through my nose (this is my second pregnancy I had the same problem with my first one also  I think I'm allergic to pregnancy lol) has anybody experienced this? Maybe I'm just weird.
