Bath tub

Im 22 weeks and I really just want to sit in a warm tub of water. If i put on my bathing suit bottoms would it be safe for me to go soak? To sooth some anxiety and back pains?

Edit:

Forgot to mention I am high risk status and just was in labor and delivery Thursday for bleeding brown/pink and 2 red clots after intercourse and then again on friday for pink spotting with no intercourse.

They said everything looks good with the little miss. And my cervix is closed

First time carrying a child and I am scared.

Edit. Talked to my ob he said I cannot take a bath :( but suggested rice heating pads for relief
