Hi OP,
There's 10.5 months between my two.
My first was an EMCS, failure to progress and I was in labour for 3 days, spiked a temperature and babies heart rate dropped a little. I think in those 3 days of (absolute agony!) contractions I only got to 3cm.
I am terrible with pain though, and I think a lot of things that happened probably didn't help me to dilate.
With the second baby the consultants actually did still try to push me for a VBAC!
I said I didn't want one, but I eventually agreed that if I went into active labour I would try for a VBAC, but if it was progressing the way my son did I would want a C section.
We booked in a Csection date anyway, but unfortunately for baby decided to come early!
Again, after 2 days of consistent contractions I was only 1cm. The contractions were unbearable. The consultant tried to convince me to go for VBAC but as I didn't want to end up with an EMCS I said no and so we had a lovely calm C-section which I don't regret!
So I think it depends on what your previous experience was like, the reason for you c section and what you'd like to do.
I think the consultants would still consider a VBAC for you if they did for me with a smaller gap.
Good luck OP
