Use breathe right strips and vicks ( i put the cream under my nose ) but it was horrible, that def helped get rid of it. Feel better
If you can get some albas oil and put some drops into a jug of hot water and leave it in the room your in especially in your bedroom when you go to sleep I find this has had me loads. Or dissolve a table spoon of vics into hot water works the same. :-)
I had the same problem at eight weeks and my on told menu could take nasal decongestant spray with moisturizer up to twice a day only up to three days in a row
Use a humidifier for sure (if you don't have one, but one, you'll need one for baby anyway), sleep propped up a bit, try using some Vicks vapor rub on your chest and on your feet (cover with socks). I hope you feel better soon!
