Can i use a hot tub at 5 weeks pregnant and if so what temp do i put it at?

No: No, you should avoid hot tub use during pregnancy. It is not recommended allow the core body temperature to go above 102.2 degrees. A soothing warm bath is a better idea.

Not advised: Spending 10 minutes or more in a hot tub can raise your body temperature to 102 F (38.9 C), causing a condition known as hyperthermia. Some studies have shown an increased risk of miscarriage and neural tube defects — serious abnormalities of the brain or spinal cord — in the babies of women who experience high temperatures during the first four to six weeks of pregnancy.

No.: Not a good idea during pregnancy. There is a risk of neural tube defects like spina bifida and miscarriage which is especially risky during the first trimester. Avoid hyperthermia to protect your baby.
