Most women know the basic tell-tale signs of pregnancy: a missed period, nausea, fatigue, and cravings. However, there are other less well-known symptoms that can indicate that you are pregnant. For example, your sense of smell may become more acute, and you may find that you are suddenly sensitive to certain aromas that previously did not bother you.
You may also notice changes in your skin, such as an increase in pigmentation or darkening of your nipples. In addition, you may find that your hair is thicker and healthier than usual. Of course, the only way to be sure if you are pregnant is to take a pregnancy test, but if you are experiencing any of these physical changes, it is worth considering the possibility that you might be expecting.
