Thanks for the response to the questions Katsma.
I am a midwifeso hope this helps
What you describe is a revealed Ante partum haemorrhage (APH)or Placental Abruption
The initial bleed from the placenta (which may have still been slightly low lying) although, frightening and a large bleed to you, was not of signicance at that time to have caused problems for the baby.
Had their been signs of fetal distress on admission, it is very unlikely that you would have been allowed to labour.
However any further loss blood loss and the stress of labour obviously resulted in fetal compromise to such a degree that delivery by LSCS was the only option for you at that stage. Either the fetal distress was very severe, or the cervix was not dilated enough for an assisted vaginal delivery.
Category ! is the most urgent for delivery.
Placental Abruption in a previous pregnancy does not necessarily mean it will happen again, no-one can ever say it will or won't.
The previous section means that you may be offered an elective section next time, or you may be offered the opportunity to try for a vaginal birth.
The decision will be yours and your obstetricians and may depend on the factors that are present in your next pregnacy, eg, no complications
Any other qustions you have I will try and answer.
