Thanks for choosing HCM,
when did you perform pregnancy
how is it done,is it a urine pregnancy test done with help of home testing kits?
its the presence of the hormone hcg
that proves your pregnancy in blood test
and urine test
yes false negative test is common in early days of pregnancy
The accuracy of a pregnancy test is most closely related to the day of ovulation, not day of intercourse that caused the pregnancy. It is normal for sperm to live up to five days in the fallopian tubes, waiting for ovulation to occur. It could take up to 12 more days for implantation
to occur, which meanseven the most sensitive pregnancy tests
may give false negatives up to 17 days after the act that caused the pregnancy. Because some home pregnancy tests have high hCG detection thresholds (up to 100 mIU/mL), it may take an additional three or four days for hCG to rise to levels detectable by these tests — meaning false negatives may occur up to three weeks after the act of intercourse or insemination that causes pregnancy.
how sure are you about the day of ovulation?
though you have regular periods sometimes you may ovulate before or after the regular time
so think of chances of such delays also
your period is supposed to be on july third so you are almost reaching august 3rd so there are less chances to get wrong results so
once again perform test at home
or go for test in a lab ,if you are not satisfied even then...
you can go for blood test for hcg
and the other way is get a scan done
meet your doctor if needed
hope i answered your query
