A good time to get pregnant

As I searched the internet for more quotes about teachers being pregnant I found a thread, "When should a teacher get pregnant?" 

Really?  Like they can plan that.  Who can plan that?  For most people, pregnancy is not something you can just say, "Oh, I'm going to get pregnant in September." For most people it is not that easy, so to expect a teacher to be able to do that is totally unreasonable.
