Can anyone tell me what type of Orchid this is?

[ThatGirlAmby]

I just bought these orchids at a grocery store recently [my very first orchids!], and didn't realize until I brought them home that they didn't tell me what KIND of orchids they were. It seems to have kind of strange thick stems... You can see one part of it in the picture with the white flowers. Both colors make up the one plant.





Thank you!
