WHITNEY Dean spent an evening with Zack Hudson and their night leads to a surprise pregnancy.
However, she isn’t the only one who could be facing unexpected motherhood next week in EastEnders.
Finlay and Felix Baker are determined to throw her the party she deserves.
The pair even manage to convince Sam Mitchell to give them a good deal on local wine bar Peggy’s.
But the celebrations won’t be going as planned for Whitney.
Making her way to the pharmacy, she bumps into fellow Albert Square resident Stacey Slater (portrayed by Lacey Turner).
The women realise they are at the pharmacy for the same reason – they both need a pregnancy test.
Yet with only one pregnancy test pack of two left, they make the decision to take them together.
Stacey and Whitney end up at No.31 to take their tests but they’re interrupted before they can tell each other the results.

Whitney goes home, hurt by Zack’s actions, and tells Chelsea he’s too much of a player to be a father to her baby.
Chelsea advises her to give him a chance.
While Whitney will struggle to keep her chin up, Zack will be looking forward to a new job as a chef at Walford East.
The heartthrob has been trying to move on from his painful breakup with Nancy Carter after cheating on her with Sam Mitchell.
