I know the spray tan place I went to (was planning a spray tan for the school formal- I'm a secondary teacher) wouldn't give me a spray tan before 12 weeks. They weren't sure it was safe so they were playing it safe. I also think it had an impact on my BF supply when I had one this year (not PG this time).

Ask your tanning salon if they will spray you while PG. Better to be safe than sorry.
