Call The Midwife viewers broke down in tears as the new BBC series kicked off with a ‘very, very difficult to watch’ premiere.

The popular British period drama, which first hit our screens in 2012, returned for its 14th series on Sunday evening. 

The first episode saw the start of a new plotline following a pregnant teenager called Paula Cunningham (Kitty Anderson).

Paula's parents Philip and Grace Cunningham think that their daughter has fallen pregnant through immaculate conception - however, that was not the case.

During an honest conversation with midwife Joyce Highland (Renee Bailey), she opened up about what happened.

While the youngster laid in bed, Joyce told Paula: 'Bodies are strange things, honey. We feed them, we clothe them and we live inside them, but we don't know them quite as well as we may think.

'And sometimes, they take us by surprise. And sometimes our bodies want things that we don't understand, but we can't run away from.'

Paula replied: 'I couldn't run away from Lenny.'

She added: 'He does nearly the same paper round as me.  Sometimes we walk back down the towpath together.'

The teen then explained that they 'have a laugh' and that Lenny has called her 'one of the lads'.

Joyce asked if the pair were alone down the towpath and Paula explained that's when they would 'play fight'. 

That is when the penny dropped for the midwife.

Many couldn't contain their emotion while watching the episode. 

One said on X: 'Two hours later I’m still crying what an absolute brilliant episode Xxx.' 

Another confessed: 'I’ve missed shedding tears on a Sunday.' 

'Just crying all the tears now (I adore this show, even if it regularly leaves me dehydrated from crying),' a third wrote.  

A fourth added: 'It’s only fifteen minutes and I’m already crying.

A fifth tweeted: 'First episode of the new season and I'm already in tears!'

Another said: 'Very, very difficult to watch. Brave Paula. #CallTheMidwife.' 

It's not the first time that the show has left fans emotional in recent weeks as they also broke down after the second instalment of the Boxing Day special.

Call The Midwife airs on BBC One and is available to stream on iPlayer.
