hi i just wanted to know if its normal when you have a cold or the flu to have blocked up ears. i feel i cant hear properly through my right ear.. also does anyone know if pregnancy affects your immune system???

it is very common to have blocked ears during the flu or a cold. decongestants usually help.

It is correct. But very importan to check all symptoms to be sure there is a flu or cold (they actually fom different viruses):
