doctors again tomorrow. got to have yet another needle stuck in me for the millionth time since I found out I was pregnant. due to my recent blood results I'm low on B12 or something so have to have a B12 jab yay so excited to be jabbed again *sigh*. anyone else had to have a B12 jab before, my younger sister had to have some a while back and apparently they hurt, my anti D one was a bit painful, is it the same sort of pain to that one or is it worse
