Hey there Serina!
Your correct answer to this question would be (<span>Human chorionic gonadotropin). As when a women is not pregnant, she would contain estrogen, progesterone, </span>testosterone, and also, follicle-stimulating hormone. These are natural when coming to a women, and her periods, this is something that she would always contain, but when this women is pregnant, she would contain <span>chorionic gonadotropin which is not normal, when not pregnant.
Hope this helps you well!</span>
