Tanning while pregnant

I've been trying to do as much research along with talking to my doctor about tanning while pregnant. Obviously it's risky to overheat. My doctor said tanning in the sun is perfectly fine, and even stand up tanning beds as long as they have a strong fan and I have a spray bottle but tanning beds cannot harm or "cook" the baby. Other sources I've read say no tanning at all. What do you other moms hear about this? My skin doesn't react well with any spray tans and self tanners, it gets completely blotchy in a day and lasts a week and it's not cute and trust me, I've tried them all!! Any advice/wisdom is welcomed.
