he feels a woman in early pregnancy
most common early signs of pregnancy first signs of pregnancy to delay: Eyes on intuition? are bouts of nausea as a sudden dizziness Dizziness - if the ground is slipping from under his feet , shortness of breath, palpitations and mild nausea.If at this time could not sit or lie down, you may even lose consciousness.This is due to the fact that pregnancy reacts autonomic nervous system, which innervate the internal organs and blood vessel walls.Bouts of nausea usually associated with a decrease in blood pressure Blood pressure - dangerous if his swing? .
changes occur in the central nervous system, a woman will feel them in full, experiencing the emergence of sudden changes of mood.So, for no apparent reason, suddenly comes irritation.Irritating all around: a familiar environment, members, family and colleagues.And if this is still something goes wrong, then the simplest situation ends with scandal and tears.But just as suddenly wash over might and great, upbeat mood and then the whole world is colored in pink.This state indicates that under the influence of the central nervous system begins to change hormones, and it is always hard to remember how in this period behaved teenagers.
taste preferences are changing and women.For someone it is more pronounced in someone less.At the same favorite dishes are no longer attracted to, and sometimes even disgust, on the contrary, that earlier did not like, has now become a vital - it wants uncontrollably, sometimes to shiver in the hands.In the mouth, there is often a kind of metallic taste that spoils even the most favorite dishes.
no less exposed to changes and smell: perfume is now revolted, and often attracts what used to be disgusted: sweetish perfume, the smell of gasoline,exhaust gases.
Finally, the sign of pregnancy may be nausea, vomiting and drooling.Often they are reflexive in nature due to irritation of the nerves that can cause such phenomena.These symptoms may also appear a week after conception.Sometimes they are very severe: persistent nausea, repeated vomiting, excessive salivation.All this is accompanied by a large loss of fluids and dehydration.In this case, talking about the first half of pregnancy toxemia or early toxicosis.It may take up to twelfth - fourteenth week of pregnancy and goes only after the placenta is formed.
