Is flu shot safe for me?

I get sick everytime I get my period cause my gynecologist said my immune system is weak and it happens when my estrogen drops every month. I then either have a bad flu or I get very nauseous. I am sick of getting sick every month. My husband ask me to get a flu shot. I've heard that flu shots have side effects. What are the side effects?

Please try this for your immune system it worked for me!!!! go to the Supermarket and buy ten bottles of "KE FIR" AND drink ONE BOTTLE A DAY FOR TEN DAYS" and stop using white sugar or drinking sodas either regular or diet. I used to have allergies every month and after them sinus infections every other week. Also, very important stop eating white flour, I know it is hard but you have to do it in order to feel better, after you finish the 10 days you can drink 4 oz. before breakfast for life if is possible, it doesn't taste bad and if you don't like milk you can find it soy base. Also, very important if your like to drink milk, buy organic milk not the regular one from the supermarket. If you do this you can see the change in a week

Some people have no side effects at all. Some people have a sore arm, mild cold symptoms or body aches for a few days after getting the shot. The flu shot will not give you the flu, since it does not contain any live virus.

Everyone should get a flu shot, unless they are allergic to something in the shot or their doctor advises them not to get the shot because of some unusual medical condition.
