Are hot baths bad for pregnancy?

I'm in the bath right now and it's lukewarm getting cold. I'm still feeling faint so I'm getting out but I've felt faint for the past few days so idk I thought it would help. But now I'm worried it's bad and the app says I'd be 4weeks 2days and I know it's a fragile time for baby but I love my baths and it is relieving the weird cramping I'm getting. I'm still getting faint positives so idk if that means it's fragile or what.
