Hi, I was just wondering if anyone would know if having an MRI on your head could effect a baby in the early stages of pregnancy? Such as implantation? I had an MRI on Moday and today I had what looks exactly like implantation bleeding and is happening in the right time in my cycle and would make sense, but its too early for me to know whether I'm pregnant or not, but I can't help but worry if I am did I just harm the embryo? Any thoughts or knowledge on this subject would be appriciated. Thanks
