Is it normal for a 39 year-old woman (her 1st pregnancy ever) to have triplets?

Anonymous

That's my aunt's first pregnancy ever and natural. She had no fertility treatment done, none. She just had C-section on Sunday and delivered triplets; 2 identical girls and 1 boy. All of them healthy babies. She's still recovering at the hospital.

We don't know have any twins nor triplets in the family. Is that normal for a 39 year-old woman's first time?

Prior to this, she had no history of previous pregnancies, nor miscarriages nor abortions. She always protected herself and got married later than usual.

The very first time she decided to conceive with my political uncle, she got pregnant fast and that's the result... the triplets.
