what are your opinions on using essential oils while pregnant? thanks!

i have a starter kit and ive dabbled with them a bit before, but im super nervous about the potency of oils being harmful during pregnancy.

i personally will not ingest any, but im still wary about topical use, like rubbing on my belly or feet, and even breathing in certain ones (like peppermint).

i have athletes foot 🙄 and am trying tea tree oil with a carrier oil, rather than anything topical until i see my OBGYN this week.
