Women can use a pregnancy test stick to determine if they are pregnant after about a week of pregnancy, but the detailed condition of the fetus needs to be checked in the hospital. Many women hope to have twins, so when can single and twin pregnancies be distinguished?
Pregnant women with regular menstrual cycles can undergo pelvic ultrasound examination around 6 weeks after amenorrhea to rule out ectopic pregnancy. If two gestational sacs are detected by ultrasound, it can be confirmed as twins. To see the fetal buds and heartbeats, it is necessary to confirm that the embryo is alive. During pregnancy, it is important to strengthen nutrition, especially for twins who require more nutrients. Pay attention to a comprehensive diet that combines meat and vegetables, eat more fresh vegetables and fruits, and consume more soy products, dairy products, and lean meat to supplement vitamins, trace elements, and protein.
B-ultrasound can show two gestational sacs at 7-8 weeks of early pregnancy, and at 13 weeks, two fetal head halos can be clearly displayed, along with corresponding spine, trunk, limbs, etc. The two children of twins come from the same fertilized egg and have the same genetic makeup, so they will be of the same gender and almost identical in appearance.
Early pregnancy is affected by changes in hormone levels in the body, and some women may experience early pregnancy symptoms such as nausea, vomiting, loss of appetite, fatigue, and weakness. Pregnant women with twins may experience early pregnancy symptoms, which are obvious and long-lasting. Sexual intercourse should be avoided during the first three months of pregnancy, otherwise miscarriage or premature birth may occur. Maintain a good daily routine, avoid staying up late, pay attention to rest, and avoid fatigue.
