Eagle-eyed EastEnders fans believe there will be a pregnancy mix-up in the near future for two of the residents.
On Tuesday's episode of the long-running soap, both Whitney and Stacey prepared to take pregnancy tests.
While they were sitting at the dinner table, the duo joked about the pregnancy tests coming in packs of two so that 'broke girls can split the cost'.
After laughing together, they headed to the bathroom upstairs to take the tests.
Viewers watched as the two spoke in code to each other and everything seemed to return to normal.
However, many people think there's more to it than Whitney and Stacey simply moving on from the pregnancy tests.
Some took to Twitter to ponder on the possible storyline of a pregnancy test getting swapped, shocking one of the characters.
One user questioned: "What if the plot twist is Whitney isn’t actually the pregnant one. They get their tests mixed up and Stacey is carrying Kheerat 2.0."
"They’re going to get the tests mixed up aren’t they?" one fan predicted a storyline.
Another tweeted: "Oh no! What if Stacey and Whitney got their pregnancy tests mixed up, that would be soooo EastEnders predictability!!"
Following the tests, Whitney 'skipped the alcohol' as she attended her surprise 30th birthday party.
Later on, viewers discover that she is pregnant (or she thinks she is) with Zack's child.
The actress who plays Whitney, Shona McGarty, previously said she 'cried' when she found out about the 'awful' plot.
Talking about Whitney's initial reaction to finding out she is pregnancy, Shona said that she is scared but admits it is something she has always wanted.

She said: "Her first reaction is she's really scared and worried! She's worried because she's not in a relationship with Zack - they were just casually sleeping together.
"I guess she just feels like she's not settled, and she's unsure about the future, and she's got to decide whether she can do it on her own. But equally, it's something that Whitney's always wanted her whole life."
According to the Daily Star, Shona said that Whitney wanted to tell Zack the shocking news but found it difficult due to him being selfish.
The soap star explained: "It's really hard for Whitney to tell him because every time she tries to, he's either so wrapped up in going to the gym or going for a run, or he's always talking about himself.
