will have fat as its content.If it is blocked in the hernial sac,you will have pain.
You can continue the pregnancy
.You can reach full term without any complications.
Your obstetritian advised for caesarean and hernia repair
at single setting.Routuinely for caesarean section
,transverse incision is given in the lower abdomen.To cover hernia in a single incision,they should give a long vertical incision from the lower abdomen to the upper abdomen to cover the hernia.
My advise is to get hernia repaired initially with cosmetically good transverse incision.Try for normal delivery.Even if caesarean is planned,it can be done by transverse incison on lower abdomen.
Wish you good health
