There are no symptoms. Some women might not experience the physical signs of pregnancy, such as weight increase, morning sickness, indigestion, or exhaustion. Or maybe they're so unobtrusive that a lady doesn't notice them. "It's reasonable for a woman to make it to 30 weeks without seeming pregnant," Cackovic adds, depending on her body type. The only way to know for sure if you are pregnant is through testing. A blood test called a beta-human chorionic gonadotropin (β-hCG) can tell you if you are currently pregnant. Your doctor will perform this test after your missed period. It's important to get this test done before any further damage occurs. If you find out you are pregnant, talk with your doctor about prenatal care options.
