Kratom -has anyone used this during early pregnancy?

My husband and I just found out we're pregnant with our first and are extremely excited! We have been TTC for about 4 months and it happened earlier than expected and I am extremely greatful. My husband and I both quit smoking and drinking (we were only social drinkers anyways) over 4 months ago. However we were taking Kratom for chronic pain - I have ovarian issues and IBS and he was in a car accident leaving him with nerve pain. We have found Kratom to be the best thing we have ever taken for our pain - it allowed us to be off of all pain pills. My question is: is Kratom okay to take during early pregnancy? I am only 4 weeks pregnant and when I tried to get off of Kratom I went through the worst withdrawal I have ever experienced and I'm scared I'll miscarriage if I don't taper off of it. We have a tapering schedule and I will be completely off of it in 2 weeks without putting the baby through my terrible withdrawal. I feel like a horrible person still taking Kratom and I am only taking as much as I need to prevent myself from going through horrendous withdrawal. There is no evidence that Kratom can hurt a baby but I am still paranoid! Is anyone else going through this?!?!?! Any help would be so appreciated! Thank you and God bless.
