The British sprinter Dina Asher-Smith had to stop running at the European Championships this week because of cramp. She said it was because of her period, and now she's calling for more research into periods and sporting performance. Hepatahlon Olympic Bronze medallist Kelly Sotherton comes onto the programme, as well as Dr Richard Burden who's co-lead on Female Health & Performance at the English Institute of Sport

We talk to Sharon Horgan and Eve Hewson, about a new black comedy series they're in called Bad Sisters. It's all about five Irish sisters, and four of them hate their brother-in-law. They're desperate for the fifth sister to be rid of him. What will they do?

We speak to Lena Kulakovska, who escaped Ukraine when she was 36 weeks pregnant and is now safely settled in Devon. She's just had a baby daughter, so what are her plans for her and her three young children?

We hear once again from listener Titania. She sent us an email when we put the call out to tell us how it feels to reach the age your Mum was when she died. We hear her story.

And we start a new series about fangirls. This week we go beyond the stereotype of the hysterical girl who's obsessed with someone famous. We ask instead what does being a fan bring to your life? We're joined by playwright and songwriter, Yve Blake, who's created the award-winning musical FANGIRLS and Hannah Ewens, a writer at Rolling Stone, former fangirl and author of Fangirls: Scenes from Modern Music Culture.
