Child Birth

So I keep seeing on here something about getting the spectrum removed or something like that when you go to give birth to your child and I have two cervix and my dr didnt remove mine I had to push past mine and tear it. Has anyone else had to do that. My Robyn didnt fix it after it tore and I'm not exactly sure what that means about it now and I haven't done any "investigating" so I'm not sure what's different now other than the septum being tore. But she said she was going to leave it alone so when I went to have another baby I would have to punch past it again. Im ttc and wondering if anyone has any tips or anything like that. I've had mc and I just want a healthy and happy pregnancy and baby. I found put I had a didelphic uterus last February. I was told before that when I had my first confirmed mc that I had a heart shaped uterus then it was corrected on February with my first check up for my pregnancy. Advice? Experiences?
