Flu shot

Megan • Trying for our third! First baby a miscarriage, chemical then rainbow. Second baby 9 months of trying 4 with clomid. Hoping for a quick easy pregnancy for #3
What are your thoughts? I was going to get one then I was told to make sure it's Thermisol free. Then why I looked that up I found many articles stating why you shouldn't get the flu shot while pregnant. Now I don't know what to do
