It is recommended to pregnancy test at least 1 week after conception, which may be equivalent to 1 or 2 weeks of menstrual delay.
Therefore, the woman should wait for the delay in menstruation to take the pregnancy screening test.
When the pregnancy test is done before that period and pregnancy is suspected, one more week should be allowed to repeat the test.
O hormone beta-hCG Can be detected at the blood or urine of the woman after the implantation of the egg (the union of the spermatozoid with the ovum) in the uterus. This implantation usually occurs 7 days after fertilization. Therefore, in the first weeks of gestation, there is still not enough of this hormone in the circulation of the woman able to test positive.
If after the test the test continues negative and there are symptoms of pregnancy, the general practitioner, gynecologist or family physician should be consulted for an evaluation.
