I know how hard it is with herniated discs. I have five herniated discs. Have you talked to your doctor about being pregnant with herniated discs. I ask because I was and it was very difficult. I was put on bed rest at five months and when I did walk to bathroom or bedroom I had to use crutches or walker. It caused an extreme amount of pain also inflammation and swelling which made me have issues with my left leg. Sometimes due to the swelling it wouldn't work our go numb and I would fall. I'm not trying to discourage you in any way and everyone person is different. I'm just encouraging you to discuss it with your physician so there are no surprises like I had. Best wishes.
