twin eating twin!!!

is there such a thing as twin eating a twin?im currently 33 weeks .when i was around 8 weeks i went to the ER cuz i was bleeding really bad like i was peeing myself. i knew i was pregnant i just didn't know it was twins i though i was having a miscarriage 😟😟but i got checked out and i only had an hemorrhage which the nurse told it was normal that i was gonna go away in the next few days then she proceeded to get an ultrasound to check on baby to make sure baby was ok there were 2 babies in there 😍😍😍i was scared and happy all at the same time i got some pictures and got discarded. i couldn't wait to get home and give my husband the knews😍he was over the moon that he called his family to let them know that he was areal man😂😂i had a fallow up appointment 4 weeks later all the bleeding stop like 4 days after the visit to the ER but they wanted me to go back once i got there got checked in the nurse try to find the heart beat but she was having trouble finding both babies so i got another ultrasound i could see two sacks but only one baby the nurse was really quiet so i asked her if my babies were ok i was kind freaking out at that point she excused herself and went to get the doctor.he started asking me questions and was making me nervous then he said he had some bad news he said one on my babies ate the other baby to be honest i was so confused and still am i still dont understand how that happened I've done some research but still cant believe it. has anyone else been tru this?
