I’ve never experienced allergies before, but this year’s kafunsho (3 month cedar pollen season) practically knocked me off my feet. It’s been awful, but I read this today on Babycenter and felt a little bit of hope for next year!
Believe it or not, it’s pretty common to have a runny or stuffed-up nose during pregnancy. About 20 to 30 percent of pregnant women have congestion without having allergies or a viral infection like the common cold. This condition even has a name: rhinitis of pregnancy. It can start as early as your second month and last until you have your baby or even a few weeks afterward. Pregnancy can make your allergies worse or cause you to be sensitive to allergens and other irritants that never bothered you before.

I didn’t know that either but I suppose with so many physical changes during pregnancy it certainly could happen. Hope it subsides soon!

I had this during the last 5 weeks of my pregnancy. I ended up getting 2 or 3 sinus infections from it. It was horrible. I’m so sorry!!!!!!
