Hello, welcome to HCM, I am Dr. Das
Look, when you have a history of c-section, the uterine wall becomes less elastic. And it may become harmful when you are going for trial. SO, to be on safe side, c-section is advised.
In your case, the gap between two pregnancy
is less. More over previously, you had multiple pregnancy.
So, you have to go for C-section. Do not try to go for trial. That will be harmful for both of you and your baby.
So, follow your doctor.
