I remember my friend found out she was having twins during her 8th-week scan when they heard two separate heartbeats. It was such a surprise! Now her twins are toddlers and running around, time flies so fast.
Usually during the first dating scan around 7 to 9 weeks, they can clearly see if there are two sacs or heartbeats. It is a simple ultrasound, no need to worry or do extra expensive tests early on.
You can find out as early as 6-8 weeks through an early ultrasound. But please consult your gynac for the correct scan timing, as they will properly check the chorionicity to see if they share a placenta, which is very important for safety.
I just delivered my little one recently and during my early 7-week dating scan, they checked for multiples first thing. It's so exciting to see the scan screen for the first time! Hope your pregnancy journey goes smoothly.
Oh, twins sound so sweet but must be double the responsibility! I think doctors can tell during the early 6th or 7th week ultrasound. I would be so shocked and happy if that happened to us.
