Pregnancy is like no other time of life, there's little denying that. Yes, some of the things that happen to your body can also happen when you're PMS-ing, when you're stressed, when you're sick, and at other times in your normal life, but, all-in-all, pregnancy can be weird and different in ways that other parts of life just aren't. Even if you talk to everyone you know and read every book there is, you're not always expecting some of the weird things that can happen even though you're pregnant. From "getting your period" to bodily changes and beyond, it's definitely more than just a growing belly, swollen ankles, and morning sickness.
Some of the things that you might experience when you're pregnant are things that you'd never expect would happen while you're pregnant. Instead, they're things that you'd think would either happen before or after your pregnancy or wouldn't be related to your pregnancy at all. Because of that, you might be a little bit alarmed or, at the very least, a bit confused, when you're waking up at the crack of dawn or dealing with a nasty cold when you thought you'd be tired during your pregnancy or that getting sick wouldn't really be something you'd have to deal with (in addition to everything else). Pregnancy is all about expecting the unexpected, but, then again, so is parenthood.
