No these are not signs of baby coming.
They infact indicate that you have a respiratory infection.
You should not ignore it, instead visit your doctor soon. This is important as mild infection if left untreated can result in complications especially in pregnancy
Meanwhile you can take steam inhalation and warm saline gargles.
Keep a record of your baby movements and your body temperature.
In case you run fever
, it definitely shows you need treatment.
