Hi everyone

Just wondering who knows about essential oil use during pregnancy.
I get an awesome diffuser for my baby shower that you fill with water, add a few drop of oil, plug in and it diffuses a mist of essential oils.

I got two oils with it an easy breathing one which has eucalyptus, spearmint, peppermint, tea tree & lemon and a calming one which has lavender, bergamot, mandarin, ylang ylang, sandalwood and patchouli.

Does anyone know if these are safe? and if the calming one would be suitable for labour?

Thanks
