What a pain! You could always go see a doctor and ask if there's anything they can give you, particularly if you show no signs at all of improvement. I had bronchitis in late pregnancy (although earlier than you, it was about 34 or 36 weeks), and I ended up getting penicillin injections to help.

Try not to worry too much though - your body is an amazing thing, and I also suspect you'll find strength and resources you didn't realise you had! The hormones that get to work to help your body labour efficiently are amazing, and you may find your nose clears for labour anyway.

As for the feeding, I agree that you'll pass on some protection from your milk, and you can help out a bit with remembering hygiene where you can. And while snuggling with a new bub is an amazing thing, it won't hurt to hand bub to dad if you need and say 'err I have a cold so I need to sleep. You can snuggle baby and just wake me for feeds '.

All the best with the birth, whenever it happens! xo
