I was/am really concerned about side effects as well, mortified that I might experience some of the really bad ones such as memory loss
gain, mood swings...but, thankfully, (fingers crossed) so far so good. I do think though that after the next shot is when I may begin to experience them, since then is when I presume I may stop having a period and hormones will be in full swing. =( I'm nervous. And I understand your concern completely!
