So my mom is trying to get back into our lives

So I never had a good relationship with my mother...she kicked me out of the house when i was 19 over nothing and hasnt supported me in anything since...i am almost 30 weeks pregnant and now she decided to call me...letting her back into my life will have an impact on my marriage because my husband does not want her in our lives because of what she has done and most importantly...of what she should have done..he has been through it all with me..it also impacted his life but he and his family have always stood by me....should I let her back in and at least listen to what she has to say? Or is it too little too late?
