The Nose May Know
Your sense of smell may go on overdrive when you get pregnant. Not only does your sense of taste change, but your nose may become more sensitive to all sorts of odors -- from cooking to strangers' perfume to your significant other. Some scents may delight you, while others may send you to the porcelain goddess for some one-on-one time.
Once your baby implants into your womb, your body temperature may increase slightly. After all, you are an incubator, and an embryo needs a warm environment to grow. This can result in discomfort while sleeping, warm, flushed cheeks and generally feeling warmer than those around you. This can be great in the winter but can be quite uncomfortable during the warm summer months.
Even from the very beginning of your pregnancy, your heart rate may be a little faster than it was before. Your body is busy building a little person, and your blood supply will increase by 25 percent before it's all over. Your body generally works harder, as well. If it's noticeable or concerns you, mention it to your care provider, but it's usually a normal part of pregnancy.
Some moms get sore nipples, while others get wildly itchy ones. And some lucky ducks get both. It's not an itch you can easily scratch in mixed company, either. With all of the changes your body is going through, and all the preparation your breasts must make before nursing a baby, it's not too farfetched to believe the skin in that area gets irritated and itchy. But don't worry -- a light coating of lanolin may help alleviate the discomfort.
