I am in a dilemma. I am 20 weeks pregnant and my OB/GYN recommended to take Flu shot. I have never taken flu shots before, not even during my 1st pregnancy. My almost 4 year old started preschool in April this year. This will be his first winter when he gets more exposure to germs. I am thinking to get one for him too. But I am not sure whether I should get one for me as well. Has anyone got flu shot during pregnancy? Are there any concerns?
