Is CBD oil safe during pregnancy ?

No negative comments please, I don’t currently use it and was never one to really partake in any type of use prior to pregnancy either. But I’ve been reading that CBD oil can help alleviate many symptoms I’m currently experiencing during pregnancy. I’m 21 weeks, and just want to know if it’s safe or not ? Have any moms used cbd oil during pregnancy? I plan to ask at my next appointment but just wanted to ask here too. TIA
