Essential Oil Use While Pregnant

Anyone use essential oils during your pregnancy? I'm 13 weeks and I'm going on day 3 of headaches 😫 Tylenol does NOTHING for me and I heard peppermint essential oil really helps by rubbing it on your temples.

I used to use essential oils ALL THE TIME in my bath, body butter, & face cleansers and know how powerful they are. I stopped using them when I found out I was pregnant.

I have seen so much conflicting info online to stay away from them completely, only use them in a diffuser only, you can use them again topically/diluted once you get into the 2nd Trimester.

Anyone know if they're okay to use?
