Things you shouldn't say to a pregnant woman...

So I went and visited my brother this past week. The day before I leave his roommate says "yeah I think having your own biological children is selfish. Uh...no offense..."

I was honestly taken aback and didn't know how to respond to that. So I didn't and just moved on, but like come on read the room. You have someone standing right there who told you that they went through fertility treatments and tried for 2 years to conceive and you're going to say that to them.
