The female body usually begins to show signs of pregnancy 10-14 days after fertilization. Some women experience cramping or a slight bleeding, known as implantation bleeding, when the fertilized egg attaches to the lining of the uterus. Others may experience deep fatigue, tender or swollen breasts, or nausea caused by soaring levels of estrogen and progesterone in the third week. Hormonal changes can also increase blood circulation, resulting in frequent, mild headaches. Mood swings and constipation are common in the first month as well.
However, the best way to know if you’re pregnant is to take a pregnancy test! Pregnancy tests become accurate about 10 days from possible conception. You can purchase one at your local pharmacy or visit a health center. Teen Clinic offers free or low-cost and confidential testing on a walk-in basis. Keep in mind that every woman’s body is different, and that these symptoms often indicate other conditions. It’s important to take a pregnancy test instead of worrying!
