Pregnant after miscarriage

Hey girls, I need your help! I had a miscarriage in October 2018, bled for 40 consecutive days. I just found out about a week or so ago that I’m pregnant again, almost 5 weeks!! I’m trying to not be too excited because I don’t want to get our hopes up. Here is my question.. when should morning sickness happen? I didn’t have it at all last time and I’m actually praying for it this time since I know that will tell me things are progressing well. I have sore breasts, very tired, and have achy legs and arms for about a week. I just want to make sure that I shouldn’t be feeling sick yet, since I have no idea when that starts. Thank you so much
