Question #2: Is it ok to tan when pregnant?

The body has an amazing temperature regulation system. It is part of the autonomic nervous system and is located centrally within the brain.  It is the thermoregulatory system. It controls our body temperature by shunting blood to the peripheral skin surfaces, dilating these vessels, and causing sweating which cools the skin by evaporation.  It sometimes malfunctions such as when we get an infection and associated fever.  The main way we keep our bodies the right temperature is by our interface with the outside world.

A fetus is cocooned within the uterus which is surrounded by fluid and by the maternal body.  These coverings isolate the fetal body from interaction with the outside world environment thus eliminating in large measure its ability to regulate its own temperature.

So,  how does this all relate to tanning?  The light rays used in a tanning booth are either UVA or UVB on the electromagnetic spectrum.  These are relatively short wavelength and have very limited capacity to penetrate solid structures including the human body.  The penetrance of these light waves is only millimeters into the epidermis/dermis of the skin and in no way could reach the fetus so well covered within the uterus.  The only possible issue could be the over heating of the mothers body which is very unlikely in a tanning booth.  Thus, it is totally safe for your pregnancy to tan in a tanning booth.  It may not be the best idea when it comes to causing skin cancers and you increase your risks of developing skin cancers by exposing you skin to these damaging light rays.  Melanoma is the most common type of skin cancer associated with sun damage.
