Your baby at 13 weeks
Your baby is the size of a large plum during the 13th week of pregnancy.
The producers
By the time you are 13 weeks pregnant, your baby has developed all of the critical body structures, the organs are hard at work. The liver secretes bile, the pancreas produces insulin and the kidneys from urine to carry waste away (into the amniotic fluid). Your little one's intestines, which have partially resided in the umbilical cord, have moved back into the abdomen now that there's enough room to accommodate them.
Head case
Baby is now about the size of a large plum, weighing less than a 28 g (1 oz) and measuring anywhere from 6.6 to 10 cm (2.6 to 4 inches). The head takes up half of that length, thanks to all that brain development during the 13th week of pregnancy. Over the next few months, the body will grow at breakneck speed to catch up. When your baby is born, the head will be only a quarter of his or her total length.
Your pregnancy at 13 weeks
Welcome to the second trimester!
Many women describe the next few months as the honeymoon period of pregnancy. The discomforts of the first trimester – fatigue, nausea and frequent urination – ease up a bit and you finally start to enjoy being pregnant. Many women even feel a surge of energy during this trimester. Know what to expect during the second trimester of pregnancy here.
Middle management
One reason why you may feel pregnant is that your waistline is starting to thicken at the 13th week of pregnancy. As your regular trousers are probably getting a little snug, you might feel more comfortable in those cute maternity clothes you've had your eye on! Whatever you decide, dress with comfort in mind.
Twin development at week 13
By the end of this week, you’ll have reached the second trimester! This week, your babies measure almost 4 inches and weigh just over an ounce. Tissue that will eventually become bone around your twins’ heads and their arms and legs is forming this week. Your little ones have also started urinating in the amniotic fluid that surrounds them.
Week 13 is a major milestone with singleton pregnancies, as the rate of miscarriage significantly lowers at the start of the second trimester. With multiples, this milestone is a few more weeks away at week 20.
