There's a lot that changes over the course of your pregnant, but unless you're trying to conceive or meticulously track your period, you might not realize right away that you're even pregnant. That means that some of the first signs that you might be pregnant could be some of the physical and emotional changes, not a missed period. If you have these surprising changes in behavior, you might be pregnant and not even know it, but because many of these changes could be due to a number of reasons, even they might not be enough to clue you in to what's going on in your body. Still, if you've noticed some curious behavioral changes lately and have missed a period, you probably want to take a pregnancy test or schedule an appointment with your doctor because there might be more to it than you initially thought.
You're probably well-aware that there are a lot of physical changes that go along with the early stages of pregnancy, from nausea to sore and swollen breasts, bloating, and more. And while the fact that pregnant women can experience big-time mood swings probably comes as no surprise at all whatsoever, some of these behavior changes are a little bit more subtle. But these early-pregnancy changes in behavior just might be a red flag that there could be a baby on the way.
