A pregnant woman has gone viral on social media after capturing the moment her baby bump "dropped" in a very rare video.
The woman - who uses the handle @nabby.nabs on TikTok - was recording her bump while at 38 weeks pregnant, when she suddenly noticed it move and drop lower.
According to the NHS' official website, this is a potential sign that the end of the pregnancy is nearing and the body is preparing for the birth. The site states:
"In the last weeks, some time before birth, the baby's head should move down into your pelvis. When your baby's head moves down like this, it's said to be 'engaged'.
"When this happens, you may notice your bump seems to move down a little. Sometimes the head does not engage until labor starts."
The expecting mother captioned the video: "Can NOT believe I caught this".
Check out Nabs' incredible video below:The video has since amassed more than 6.1 million views since being posted on the social media site, with thousands of TikTok users flooding the comments section with their reactions and thoughts.
"Every day I realize I literally know nothing about pregnancy," wrote one TikToker.
A second added: "I dropped while standing in a Macy's. An older woman saw it happen and started crying because she thought it was beautiful."
And a third commented: "Have had two kids and have never felt 'the drop'. This was amazing to watch."
Meanwhile, another simply added: "THERE'S A DROP??"
In a follow-up video, Nabs explained how she felt in that moment, saying: "What I felt was a light tug. And it was more 'forceful' - it wasn't like a huge force - it was more noticeable movement in that moment than at any time in my pregnancy."
The TikToker also added that despite the drop occurring, she didn't actually notice the change in her bump until two days later, when she was showing off her stomach on Facetime.
"It just didn't look like me - my entire pregnancy," she explained. "So I hadn't known that I actually dropped until that picture was taken on Facetime and we did a comparison."
Nabs has also shared that she has given birth to a beautiful baby! Congratulations!
