10 symptoms that tell you you might be pregnant

　　1. Aversion to food
　　
　　While some women insist they crave certain foods during pregnancy, food aversions are even more common. You may suddenly find that certain foods you once enjoyed are now completely disgusted. This feeling may come and go several times throughout your pregnancy.
　　
　　2. More sensitive to smells
　　
　　It's a very common phenomenon among newly pregnant women that they'll be tempted by a bologna sandwich or coffee Or some special smells may make you more sensitive or even cause vomiting. While no one knows exactly why, it may be a side effect of the rapid increase in estrogen in your body.
　　
　　3. Fatigue
　　
　　Feeling suddenly tired is not, that is not exhaustion. As you adjust to the increase in progesterone in your body and the stress your body is experiencing, you'll feel like you ran a marathon at the end of the day. You will start to feel more energetic, albeit tired, in the second trimester, and this fatigue is usually more pronounced in the third trimester.
　　
　　4. Frequent urination
　　
　　Soon after becoming pregnant, you may find yourself going to the bathroom frequently. Why? This is mainly because blood and other fluids in the body increase during pregnancy, causing extra fluid to flow through your kidneys to your bladder. The symptoms can start as early as six weeks into the first trimester and continue to worsen as your pregnancy progresses and your baby puts extra pressure on your bladder.
