Probably just a cold virus but good to test for Covid just in case
I had a sinus infection through most of my pregnancy especially in the beginning months and towards the end around 30-40 weeks. Nothing I did help. All I can say is saline and maybe check your blood pressure.
Test is negative just a bad cold I have thank you everyone x
This time of year the cold/flu is very high and common. I’ve found I’ve also got blocked sinuses and ears popping but midwives told me that was normal! Headaches also common. I wouldn’t worry too much and test to make sure! Xx
