Are baths ok when ttc?

I like to take baths to relax but is it ok to take if ttc? Does it mess with fertility? If I become pregnant after ovulation but are still waiting to test, can a bath cause any problems with implantation or holding a pregnancy? I heard its important to stay warm after ovulation to aid implantation so I would assume baths would be a good thing to help stay warm. Any advice would be helpful. Thanks.
