Hi everybody me trying to have a second baby for many years, but today I miss my period for three day but pregnant test is negative what should I do test again everyday or thank you.

You can try testing again after 4 more days. Pregnancy test kit work by detecting the presence of hormone hCG in the urine. Within the first few weeks of implantation, the amount of hCG secreted by the woman’s body doubles every 48-72 hours. Hence, by 7 to 10 days after ovulation, a highly sensitive home pregnancy kit should be able to detect the hCG present in the urine. Therefore, one week after a missed period would be a good time to test.
