Fibromyalgia and other chronic illness sufferers

I have fibromyalgia and another very serious rare chronic diagnosis that both cause me incredible pain. I am 5 weeks and 4 days pregnant and am wondering how pain is managed during pregnancy? I'm currently prescribed fentanyl patches (low dose) and oxycodone as well as muscle relaxers and am on weekly Humira injections for arthritis. I have my next OB appointment tomorrow and intend to go over the plan with her, she knew about my medications from the start and just told me to continue as usual, but I am worried about baby. There is no way I can manage with zero pain relief but want to do the best I can for my baby. I'm categorized as high-risk based on my diagnosis so I am in good hands. Just curious as to whether or not any other mamas have been through this and what your experience has been.
