Aunt feeling is also known as the feeling of menstruation, the strong feeling of menstruation can not determine whether there is pregnancy. Women with menstruation may experience discomfort in the lower abdomen and lumbar-sacral area, gastrointestinal disorders, breast swelling and pain, fatigue, drowsiness, etc. Individuals may experience mood changes, such as agitation, irritability, headache, dizziness, sleep disorders and other symptoms. After pregnancy, women affected by the level of estrogen and progesterone in the body may experience discomfort in the lower abdomen and lumbar-sacral area, breast swelling and pain, fatigue and weakness, emotional instability and other symptoms similar to the feeling of menstrual flow. However, these symptoms are not diagnostic of pregnancy, and a urine test or blood test for HCG is needed to diagnose pregnancy. To determine whether you are pregnant after intercourse, you can’t rely on the feeling of your period, but need to take a urine test or blood test for HCG to be more accurate.
