Congratulations, you’ve made it to the second trimester. Here’s what to expect when you are 13 weeks pregnant with twins:
By 13 weeks in the twin pregnancy each of your twins is 2.9″ (7.4 cm) from head to rump and weighs 0.8 ounces (23 grams) and averages the following measurements:
Head circumference: 3.5″ (89 mm)
Abdominal Circumference: 3″ (76 mm)
Femur Bone Length (about from the waist to knee): 0.5″ (13 mm)
Each baby is about the size of a pea pod or lemon.
What to Expect
Typical weight gain for Mom at this point is between 1 to 1.5 pounds/week (0.5 to 0.7kg).

What to Prepare This Week
When Mom is 13 weeks pregnant with twins, it is a great time to find a local group for fathers of twins. This will give you a local support group that you and your family can rely on during the twin pregnancy and beyond.
By the time Mom reaches 13 weeks pregnant with twins, you are entering the 2nd trimester. This is typically the sweet spot where life gets a little easier for Mom. Morning sickness should be fading and she still isn’t so big that life is miserable. As the 2nd trimester ends, she’ll start to be very large and uncomfortable. Take the current window of opportunity to prepare your home and family for the twins.
