During Pregnancy

I feel like I remember having read something about this on these boards before, but a search didn't find what I was remembering, so apologies if this has been covered before, but:

When you're pregnant during which visits will the doc do an internal exam? Is there ever a rectal or breast exam or anything else?

None of my friends have been pregnant yet, so I've never talked about this with anyone who's been through it, so I'm very curious!!

At my wife's pregnancy exam she got a breast exam and an internal exam without getting a rectal exam.
