Don’t worry if you are not assured about your period’s dates or your conception time. Your practitioners still determine your due dates with the following things on your very first appointment:

  • Your pregnancy date can be estimated by early ultrasound. But wait not all women get an early ultrasound. The schedule of these scans is set by your practitioner. You could have several scans throughout pregnancy or just one. Why one? Several factors are taken into the account before going for an ultrasound scan. So if you are 35 above, had any miscarriages or pregnancy complications before, or having irregular periods. In all these cases, you will go for only one scan.
  • It will also tell you when the baby’s heartbeat can be heard that happened around 9 to 10 weeks. Plus, the baby’s feet fatal movements can also be told, which would be between 18 to 22 weeks, but it can be varied.
  • Your uterus can also be helpful to find out the estimated delivery date by its size. Which will be monitor during your first internal pregnancy exam.

Can my due date alter?

Yeah, it is possible that your expected delivery time can be changed. It is very normal and your doctor will let you know about it as your pregnancy progresses.

The reasons for changes in due date are many. Maybe because of your irregular periods, the first ultrasound scan was in the second trimester. Another reason could be your abnormal fundal height or your alpha-fetoprotein (AFP) levels. A protein produced by the baby is higher than normal. If you have any questions or concerns, speak with your practitioner.
