I just got over 3 colds which led to me developing bronchitis. Ugh. Get that mucus up now before it starts heading down further into your chest and you end up like I did. If you're coughing up mucus, good! You wanna continue to cough up the mucus until your chest is clear (your cough won't tickle any longer). If you're coughing a lot on and not bringing much/anything up, you need to thin out the mucus so it will come out - the humidifier will help with that. So will sitting in the bathroom with the door closed for a maximum of 15 minutes (I do 10) to be completely safe for baby. Right before you open the door, force yourself to cough a bit. It will help looen what's in your chest.
I also use hot chamomile tea with honey. Raw apple cider vinegar mixed into warm water with raw honey if you have these items. This works a treat. Eat bananas to treat the cough during the day but NOT at night. My dr allows Robitussin (DM) but doesn't recommend any medications until after 12 weeks along. I'll update this as I remember more things you can do...
Gargling salt water (1tsp sea salt, 1cup warm water) is great because it helps soothe the throat and helps kill the germs causing you to be sick in the first place! Lemon is great for helping kill these germs, too.
