pregnancy manners

Ni
Im 17 weeks now and have been hearing how people have no manners around pregnant women. Well It happened...This random lady at work goes "wow you rly popped" in passing. Like why would you ever make a comment unless you knew someone was 110% pregnant and even then you should be a close confided in colleague not a random one from a different department! I was in disbelief that someone would actually be so inappropriate. I guess there will be more bad manners to look forward to!
