welcome to hcm, I really appreciate your concern, No its not sign of pregnancy. .In fact different women experience different early symptoms of pregnancy but the most common symptoms are:1.spots and cramps,usually happens one week after the egg is fertilized. 2.swollen and sore breast,also the areola may become darker. 3.Fatigue,the woman feels tired,has no energy and the rest is very important. 4.nausea,is very common in pregnant women,especially in the morning. 5.there are other symptoms which appear such as:frequent urination,constipation,headaches and dizziness etc.i would advice you to do a pregnancy test if you think you are pregnant and then to consult your doctor. Please let me know if you have any further questions. Thanks. regards.
