hot bath in pregnancy trimester 2

Hi, Moms. Now I'm in the second trimester and, for some reason, I often feel very achy. Yesterday, I came home from work and soaked in the bathtub with warm water. It felt so good to relax and it really helped me sleep soundly afterward. But I just found out that hot baths are not allowed during pregnancy? I'm really panicking. Has anyone else done or experienced the same thing?
