Please help!

I saw a trailer today. A blonde actress, wearing a green dress or top was speaking to dark haired women in an off white pea coat, they were sitting outside. They were speaking about kids, the dark haired lady had twins and the blonde asked her about IVF. The dark haired woman mentioned needles. The scene switches and the blonde is home, and you get the feeling she doesn’t believe what the dark haired woman was saying.

(I don’t know if it was a movie or series)
