You will get stretch marks.

ON YOUR BOOBS.

You will be expecting the belly stretch marks. You've been warned about those for years! So you are pleasantly surprised when, halfway through, you haven't seen any yet. You know your time is coming, but this is nice.

And then you check out your (gargantuan) boobs. Lo and behold, there are the evil little marks you have been fearing. On your ladies. These flattering marks will make you feel very beautiful indeed.

When your husband finds you sobbing on the bathroom floor, don't even try to explain.
