Many women confuse the initial, earliest signs of pregnancy with the changes typical of the onset of the menstrual cycle, since both conditions are very similar in sensations. Literally 8-10 days after ovulation and the release of a mature egg into the fallopian tube, after meeting it with a spermatozoon and conception, successive changes in the female body are formed. They are associated with the influence of the key pregnancy hormone - hCG.
Therefore, approximately 8-10 days after ovulation, unusual symptoms that occur may be early signs of pregnancy. However, if a test is carried out at this time, it can give a negative result, since the pregnancy hormone (hCG) initially rises in the blood plasma, and only after a while begins to be filtered into the urine, where it is determined by the tests.
