Strictly speaking, the symptoms of pregnancy will not be very different from what you feel during the first month. You will feel nauseous, dizzy, very tired and you will be urinating frequently. Amidst all this, your moods will swing.
You will develop cravings for certain foods or smells just as strongly as you develop aversions to certain other foods or smells. To those who smoke or consume alcohol, doctors believe this is the best time to give it up, if you have not already done so, because it really harms the baby’s development.
Hormonal changes make an impact on your entire system. Like, your intestines may get rather stiff and make you constipated. You will need to consume a high-fibre diet. Your breasts will become tender and larger and develop nodules around the areola, the dark portion around the nipples. Your skin may develop the classical glow of pregnancy. Or, you may even develop acne.
As a lot of things begin to happen during this month, the visits to the doctor also begin as per a time-table. The doctor will test your urine and blood for various indicators. It could be diabetes, iron deficiency, or any other infections. Your blood will also need to be monitored from now. All these are very important.
As for the baby, this is the time when the embryo is well on its way to developing as a foetus. It is a little over 5 cm long and weighs around 14 gms. The amnion sac and yolk sac start developing. The heart starts forming its four chambers; the neural tube that joins the brain and spinal cord later on, also starts closing; the placenta through which the baby will get nourishment also starts developing.
Major organs like the brain, lungs, stomach and liver begin to form. Also, ossification, the process of hardening of bones and joints, occurs at this stage.
In an ultrasound, you will be able to see a minuscule formation, but it doesn’t resemble a human body yet. Tiny arm buds in the early part of the month will slowly convert into arms by the end of the month.
