Its normal im 30 weeks n ive had all of those symptoms throughout this whole pregnancy.
It seems to be normal, I'm on my third pregnancy and didn't experience it until this one but I've had such a stuffy nose and an awful choking like cough but luckily it's starting to go now, I'm 37 weeks and 3 days. Honey and lemon and lozenges helped loads, but there's not much they can give you when pregnant.
