In fact, some signs actually appear early; one to two weeks after fertilization. This applies, in the first place, to vaginal bleeding. In the case we are talking about, it is implantation bleeding when a fertilized egg gets to the uterus and tries to attach itself to its wall. At the same time, slight pinkish discharge may appear, which are not accompanied by painful sensations (well, unless by stress) and quickly pass. This happens on the 6-12 day after conception. But, keep in mind that this symptom is not present at all in pregnant women. Implantation period in many women passes without any discharge.
After 7-14 days, painful sensations may appear in the chest, which becomes more sensitive and elastic. The woman notices that the nipples swell and darken, of which several drops of colostrum may be released during the first weeks of pregnancy.
If a woman is not diagnosed with diseases of the gastrointestinal tract or food poisoning, and she is occasionally disturbed by nausea and sometimes vomiting, then most likely it is another early symptom of pregnancy. It manifests itself already from the second week from conception.
14-20 days after the onset of pregnancy, women may manifest unknown food predilections and/or complete intolerance of previously loved foods.
A few days before the start of the expected menstruation (as well as 3-4 days after its delay), the woman has an increase in basal temperature.
And, finally, the delay in menstruation is the surest early sign of pregnancy. But do not forget that in some women with the appearance of the first signs may well be even menstrual discharge. True, they are less intense and longer than usual.
