There are still 10 days from menstruation to find out if you are pregnant, because women’s ovulation is just 4 days past, if you have sex and get pregnant, the fertilized egg is still inside the fallopian tube, has not entered the uterine cavity, not to mention the bed, and has not secreted chorionic gonadotropin, whether it is to do a blood test or urine test, can not be detected as pregnant. It is best to go to the hospital 7 days before your period to get a blood test, if you are pregnant the HCG is higher than normal. If you want to do the test yourself, you can do it when your period is due and it will be more accurate. The hormones secreted by the larger embryo after pregnancy will increase, and the test will be more accurate.
