Secertly Online Bullying

I use too get bully alot in school , and it was horrible for me. It got to the point where it got physical , i got pushed down stairs . Stabbed with a pencil . My hair pulled . You name it it happened . Well recently the same people that been bullying my found me online , and sends me horrible messages . Saying why am i still alive just real bad things if they see me they going to beat me up . Im a really quite girl , and normally stay to my self , but im hidden it from my husband . He knows how much i have gotten bullied in the past and i dont know how to tell him . Cause recently i just found out i was pregnant as well , honestly i dont know how too take the threats. Should i tell him or just leave it alone . Need some advice please .
