PLEASE! This is an emergency!! My biology science fair is due in four days, and I have a HUGE problem. I was suppose to get pills or liquids that contain hCG, then add different substances to it to see if the pregnancy test would still read positive, but when I went to the pharmacy today to get them, I found out they are for prescription only .. does anyone know anything that contains hCG that I could get without prescription?!?!?! please!! id really appreciate it!
