Can catching the flu cause complications with my pregnancy?

Yes. Unfortunately the flu during pregnancy can be devastating. If you can get a flu shot, it is safe at any point in pregnancy although some like to wait until after 12wks. For whatever reason, the flu can become more invasive & produce lung failure and death more often in pregnancy.In my local I am aware of 2 we lost in one flu season.
Definitely . That is why every pregnant woman should get the flu shot!'.
