It is generally considered normal for the baby to be positioned downward in the uterus at 7 weeks and 4 days of pregnancy. However, if there are concerns about the baby's growth not matching up with the gestational age, further investigations such as an hCG test may be recommended by your doctor. The hCG test helps measure hormone levels and can provide additional information about the pregnancy. It is important to follow up with your healthcare provider for any concerns or questions you may have regarding your specific situation. They will be able to provide you with personalized guidance and address any potential issues that may arise during your pregnancy journey.
