7 Weeks Pregnant

What to expect at 7 weeks pregnant? Week 7 of pregnancy marks an important development phase of the brain. Your baby is generating about one hundred brain cells every minute, her arm and leg joints are forming, and her heart is becoming increasingly complex as well. Fetus is now about 0.5 - 1.3 centimeters long — the size of a red bean. This week comes with many major changes, and your baby will soon start to develop other vital organs.

What to Expect:

  • During the seventh week of pregnancy, your uterus doubles in size, which often makes eating a chore due to morning sickness (nausea and vomiting). Interestingly, you now have 10 percent more blood in your body than before you were pregnant. The increased blood volume, together with the extra fluid processed by your kidneys, will cause you to urinate very frequently, but don’t worry. Use the bathroom as many times as needed to empty your bladder.
  • By the end of pregnancy, you will have 40-45 percent more blood in your body, and the growing baby will put a lot of pressure on the bladder, which will send you to the bathroom more frequently as well.
  • Morning sickness won’t go away until week 14-16, so don’t expect nausea to ease up very soon. The amount of vaginal discharge is on the rise at this point, but this shouldn’t concern you. This fluid will keep infections at bay, and maintain the vagina’s acidic pH environment, so there’s nothing to be concerned about.
  • When you're 7 weeks pregnant, your breasts are probably quite uncomfortable at this point, and will become even more so as your pregnancy progresses. Wear a sports bra to alleviate the discomfort, and avoid touching your boobs. Constipation may also kick in during the seventh week of pregnancy, but you will probably want to avoid any medication to prevent further complications.

Your Baby at 7 Weeks

How big is a baby at 7 weeks? Your baby is growing at a rapid pace, and his embryonic form will soon transform into a little person. His/her hands and feet are emerging from the growing buds that will soon become his arms and legs, and he/she has already gone through three sets of kidneys so far. During week 7, the fourth set will start to develop, and this set will be ready for waste management. Amazingly, your baby will form urine during the next few weeks, which will also become part of the amniotic fluid.

Your baby has a something of a tiny tail, which is essentially an extension of the tailbone. Don’t worry — the tail will soon disappear! The baby’s liver is churning huge amount of red blood cells. When the bone marrow is fully developed, it will take this task over. The teeth and palate are forming, while ears continue to develop. The baby’s skin is as thin as a sheet of paper, and the blood vessels are clearly visible.

Pregnancy Tips

  • If you’re curious about when your little one will be arriving, you can talk to your doctor about this, or calculate 9 months from the first day of your last menstrual period. This will help you make sure that everything is in place before your little one arrives.
  • It’s important to stay fit during the course of your pregnancy to avoid any other hormone changes that might impact the development of your little one. Avoid being around people who are unwell during this early stage of pregnancy. Illnesses like rubella can be very easily transmitted, and they may cause many complications.
  • Also, if you have a cat, you may want to get your partner to clear the litterbox, because contact with cat poop may cause toxoplasmosis, a parasitic infection.
