Pregnant with Fibromyalgia

Just found out I’m 5 weeks pregnant and I am over the moon. However, reality is beginning to set in and I’m a little scared. Is my body going to be able to handle it? Will my immune system attack the baby? When I had my first child I wasn’t sick. My doctors believe that my fibro was triggers when they hit my root nerve during my epidural. My doctors are pulling me off of all my support meds to protect the baby, but the unknown is making me anxious. Has anyone else with fibromyalgia had positive/negative experiences with pregnancy that might help me? Was there anything that helped you?
