The longer you wait, the better. Certainly more than 18 months, minimum.
Yes, it's possible... happens every day, but make an informed decision. For every 20 or 30 or 40 successful VBac stories, there may only be one or 2 nightmares & some proponents of VBacs will say that the ".02% chance" of something going wrong isn't enough to warrant a repeat Csection...... but if you ask the one who lived the nightmare, their perspective would be very different.
A repeat Csection saved my uterus & my child's life. There was no indication of anything wrong, but once opened up it was discovered I'd already begun to rupture on my previous uterine incision. I had no clue because of the scar tissue.... no nerves so no pain. If I'd opted for the Vbac, I likely would've lost him.
