C section

So I had my first son naturally. My second son was emergency c section as pre aclampsia kicked in. I had a miss carriage in July, iv been blessed to have found out I'm carrying our rainbow baby. This time there keeping a very close eye on me via scans etc and blood pressure going through consultant this time instead on mid wife. The one thing I really don't want is another section. What's the chances they will let me have another natural? Anybody else been through anything simular? I'm only 6 weeks the midwives iv seen I.e at the scans and appointments won't tell me anything as I'm losing a lot of blood all ready all the time? Any help and advice Muchly appreciated x
