Asked: Can anyone tell me what movie this is?

I can't remember any actors/actresses. But I remember things that happened, like:

– It's mostly a flashback movie, I believe, and it's where a group of women get together again in a treehouse I think.
– The girls, in the flashback, had gone to the cemetery at one point (I feel like it was to do magic, but idk)
– There was a "homeless" guy that people said bad things about, but he was really a nice guy who saved one of the girls from falling into a… sewer, because it was raining really hard
– I think one of the girl's parents' were getting divorced
– They also visited a psychic woman and rode their bikes everywhere
– It's an oldish movie and I know there's some famous ones in it.

That's pretty much all I can remember, oh and I think one of the women was pregnant and went into labor at the end of the movie and everyone is trying to rush her to the hospital XD I thougt Rosie O'Donnell comes out in it, but, I might be wrong. Thanks in the future! 🙂
