This mom has an extremely rare pregnancy known as Superfetation where a woman can get pregnant while already pregnant.
Superfetation happens when a separate egg is fertilised by sperm in the womb days or weeks after a pregnancy has already occurred.
This is what happened to the Tiktok user known as @The BlondeBunny1, who is now about 17 weeks with her triplets.
In the video that went viral with more than five million views, this mom explains what is happening inside her belly.
"We knew it was two separate pregnancies. When you ovulate, you ovulate 24 hours. And the sperm can live in your body for up to three to five days. So our first two babies are 10 and 11 days older than our third baby."

Doctors are monitoring her with ultrasounds every two weeks so that they can confirm that it was, in fact, superfetation and not twin absorption or a malnourished baby.
@The BlondeBunny1 says that their third baby is as healthy as the twins. Growing at a healthy rate just like the first two babies, she says.
She thinks that this happened to her because her hormones did not stop her from ovulating. She ovulated the second time.
In one Tiktok clip, she explains that her mucus plug had yet to form, which allowed a second pregnancy to happen. At the time this happened she was not taking any fertility drugs, and she does not have a bicornate uterus.
This mom says that she is lucky enough that her babies are close enough and will have the same due date. "We just need to get the third baby past the 28-week mark, and hopefully carry them to 32, maybe even 35 weeks," she said.
