Degenerative disc disease

I am 30 weeks and my back is flaring up now more than ever. When my now 5 year old was 1, I had xrays taken and was told that I had severe degenerative disc disease and the last 2 discs had almost non existent padding. It has flared up and hurt over the years if I of course move wrong. With this pregnancy it's the worst I think it's ever hurt. Now my pelvis has started spreading and making the pain worse. I have been working out for 3 years to help alleviate the pain but I'm not so sure if I should continue anymore throughout this pregnancy. I'm so sad and in so much pain.
