Yes, but it shouldn’t be as hot as the water found in a hot tub.
Before you give up your relaxing time in the tub, you should know that your evening soaks are perfectly fine, and can actually help relieve the uncomfortable back pain or muscle aches that sometimes happen in pregnancy. However, you should not make your bath water so hot that it raises your internal body temperature in the way that hot tubs can. This is because we know that prolonged exposure to very hot temperatures can increase your risk of miscarriage and birth defects. So enjoy your bubble baths now, but avoid overheating to the point that it could be dangerous.
