If i could recommend anything It would be to go into ur bathroom and close any doors or Windows and turn on the hot water and just sit on the toilet or somewhere comfy. It works better than a humidifier in my opinion. It's worth a shot. Good luck. Also hot tea with lemon and honey.
I had a cold for 3 months it was horrible they eventually have me z pack... it took 2 packs to get rid of it
I took Robitussen and eventually was put on Amoxicillin for my cold because it kept coming back! Ask your doctor what they recommend.
The nose bleed is normal for pregnancy, don't be scared. The cold olso, just try to drink as much water as you can, take C vitamin and eat fruits, this will help..is better then nothing :-)
