Bad BO after having my baby. What to do?

Marissa
I am 9 weeks pp and the beginning of this week I noticed that I have really bad BO. Before I was pregnant & when I was pregnant I never even had to wear deodorant because I never sweat and I never smelt ! Now I am freaking out because I don't sweat but I have bad BO! (Eewwww😷😷😷) has any other mommies had this problem? When will I go back to normal? What can I do help???
