Tanning with pregnant

Does anyone else here tan? If so what have you been told about tanning while pregnant. I'm almost 5 weeks I've been going tanning like normal but wondering what everyone has been told. I had a miscarriage in oct hoping this one will stay with us. I usually go 15-20 min I used to never use the fans but I've started. I'm not getting hot (i don't feel hot like with no fans) I usually go 1-2 times a week
