It is possible that a sore stomach is a sign of pregnancy. This is because after pregnancy, as the uterus increases in size, some women may experience soreness and pain in the lower abdomen, but usually this discomfort in the lower abdomen is relatively mild. The diagnosis of early pregnancy usually begins with a history of menopause, and early pregnancy reactions usually occur around six weeks after menopause. The manifestations of early pregnancy reactions are various, including dizziness, weakness, drowsiness, nausea, vomiting, preference for acidic food, and some women may experience mood changes when they are first pregnant. You can buy early pregnancy test strips to test your urine at home when your period is delayed for a week without coming. If you want to know if you are pregnant as soon as possible, you can also go to the hospital for a blood test. The blood HCG test is not only sensitive but also very accurate and is now widely used in clinical practice. A positive pregnancy test in blood or urine indicates pregnancy, but a positive pregnancy test only indicates pregnancy, and an ultrasound is needed to determine if the pregnancy is intrauterine.
