7 weeks pregnant symptoms.

Nausea: Morning sickness may be going strong at 7 weeks of pregnancy. If you expecting twins, morning sickness is probably worse due to highest levels of hormones. But don’t worry it should get better after the first trimester. Some moms-to-be finds relieve taking Ginger natural tea or vitamin B-6.

Food cravings and/or aversions: You probably find yourself craving for weird foods. Same as not wanting to eat foods that you thought was delicious before. Don’t worry all of this is normal. It is ok to give in to your cravings and indulge once in a while. But try not to go crazy, and make healthy food choices instead when is possible.

Mood swings: Not only your hormones are all over the place but you can be feeling emotional and overwhelmed by the idea that you are pregnant. Don’t worry it will get better soon.

Frequent urination: Your uterus at this point even though you don’t look pregnant has doubled in size. Also know that your uterus anteriorly is pressing against your Urinary bladder.

Acne: Breakouts in multiples areas of your body are due to hormonal changes. You can use certain products to ease the symptoms, but please before you use anything check with your doctor if they are safe to use while you are pregnant.

Cramping or spotting: Sporadic mild cramping with pink or brown spotting can be normal. After all, your uterus is growing rapidly and your cervix must be sensitive too. However, an Ultrasound is always recommended to Rule out miscarriages.

Fetal development at 7 weeks.

The embryo starts to folds on itself and getting longer. By now your 7 weeks baby is looking like a tube rather than a small ball.
The cells starts to become three distinct layers, from which organs will arise( outer, middle and inner cell layers )
The outer layers develops parts as complicated as the brain, skin, hair, nails, tooth enamel.
The middle layer grows into bones, muscles, blood vessels, blood, the heart and part of the lungs, it also develops the kidneys and reproductive organs.
The inner layer forms the liver, intestines, urinary organs, and another part of the lungs.
The nerve cells that will become the brain have started to form.
The neural tube is still developing, this later will form the spinal cord, connecting the brain with the rest of the body.
Arm and legs are recently formed and growing.
