Cinnamon while pregnant.

D.💋
So, I'm 30 weeks. But I just read that its bad to ingest cinnamon oil during pregnancy? I made rock candy, of course with cinnamon oil and then I kinda wondered if it was okay or not after I started eating it. But I eat red hots and French toast like crazy.. Just that the oil only is bad. Has anyone else heard this? Is it safe to eat my delicious rock candy? Lol
