Hi: try SInucleanse nety pot is a natural wash to clean your nose, it is a small plastic pot like an Aladin lamp, it comes with some pockets with natural saline solution packets, At first it is kind of discomfort for the saline in your nose,but you will get used to it,, the salt it is the best desinfectant and cleaner.. I had allergy sinus with bad smell,and that has been my cure, I clean my nose every night now.Go to any pharmacy or www.sinucleanse.com. Good luck
The first question is: Does the “bad smell” originate in your nose or hers? There are isolated reports of a heightened sense of smell during pregnancy. There are also reports of individuals experiencing bad smells, with nothing to account for it, either in the nose or in the general environment.
Before embarking on a search for the cause of the alleged malodor in your nose, you should seek independent confirmation by a third party, preferably another family member. If your wife is right, you might want to first try some nasal washes 3 to 4 times daily. To learn more about this technique please read our nasal wash treatment information by copying and pasting this address

into the address window of your internet browser.
If that fails, you may want to seek a medical examination in a public clinic if one is available in your city.
Good luck.
