my turn to rant!

I went to my first prenatal appointment today and my doctor said I should get the flu shot because now that I'm pregnant, it would be more of an issue if I got the flu. So I went ahead and got the shot. When my mom found out (I'm 21 and married and live in a different state, by the way) she FREAKED OUT. She told me it would harm the baby and that I would have a bad reaction to it and that I should sue the doctor. 
It totally sucked the joy right out of my day for her to yell at me for something she knows nothing about. Ugh.
