progesterone shot made me nearly pass out

Regina
I just had the first of my weekly progesterone shots ( to keep the baby in... I delivered prematurely last time). I nearly passed out, went numb and sweaty and felt nauceous. Has this happened to anyone, where the medication has made you feel that ill? I'm just curious if I'm alone on this.  (They will try again next week and see if it happens again and if yes I suppose that idea is out!)
