Ob-Gyn questions? Ask a gynecologist online.
Like I already explained, this process is definitely a 100% impossible. If one baby stays alive, test remains positive and bleeding doesn´t occur.
if there are still open questions, I will be glad to answer them.Otherwise please don´t forget to honour my work with a kindly rating.
Thanks a lot, all the best for you,
Dr. N. Scheufele
