This is officially the last week of your first trimester! Here’s what’s going on with you and baby this week!
Your Body at 13 Weeks Pregnant
Your uterus is large enough to fill your pelvis, and you might be able to feel it between four and five inches below your navel. In the coming weeks, your uterus will begin to expand above your pelvis!
You probably haven’t needed maternity clothes before now, but you will need them shortly! You might want to look into getting some good maternity clothes for the months to come! You may not need them quite yet, but you will soon!
Another good thing that comes with the thirteenth week of pregnancy is a reduced chance of miscarriage. At thirteen weeks, your chance of losing your pregnancy reduces drastically. Because of this week being “safe,” many couples choose to refrain from sharing their good news until now, so if you’ve been keeping mum, you might want to share the good news now!
You might be experiencing round ligament pain. This pain comes in sharp, crampy and achy feelings on the right and left sides of the uterus, where the round ligaments are located. Switching positions more slowly may help alleviate this pain, and simply relaxing might help.
By now, morning sickness should be letting up, if it isn’t completely gone already! You may also enjoy feeling more energetic during your second trimester; a great reprieve from the fatigue associated with the first trimester!
Your Baby at 13 Weeks Pregnant
Your baby now measures between 2.6 and 3.1 inches long and weighs between 0.5 and 0.7 ounces! Your baby is the size of a cherry tomato.
Your baby now has her own fingerprints! These fingerprints are unique from everyone else’s in the entire world, even identical twins don’t have the same fingerprints!
Your baby’s veins are visible through her thin skin. She dosen’t have much, if any, fat on her body quite yet, but she’ll get there! Your baby’s intestines had been located within the umbilical cord, however, they are now migrating into her abdomen this week, where they will begin to further develop your baby’s digestive system. Your baby’s tiny pancreas is even beginning to produce insulin this week; a substance that will help your baby to regulate her blood sugar for the rest of her life!
All twenty of your baby’s tooth buds have formed and are located underneath her gums. She is also swallowing amniotic fluid and passing it through as urine. Your baby’s body isn’t proportionate yet, but her body is starting to catch up with the size of her head!
Prior to this week, your baby’s eyes had been located on the sides of the head. They have begun to migrate towards the front of the head, closer to their final position. The eyes won’t be in their final position quite yet though, and they may not reach it for another couple of weeks!
