I am also trying to conceive and keep tracking everything so closely. But actually, from what I read, one week is very early to know because implantation itself takes more time. It is better to wait at least till your missed period date to test.
When I was staying at my parents' house, my mom used to tell me to have patience and not rush. In just one week after conception, even urine tests can't detect the hormones properly. Just stay happy, eat home-cooked food, and test after a couple of weeks.
I totally understand that sweet excitement and the urge to know right away! But please give your body some time, dear. One week is too soon for the pregnancy hormone to show up on home tests, so try to distract yourself for a few more days.
Ek hafta toh bahut jaldi hai, behan. Humare ghar pe toh bade bolte hain ki sabar rakhna chahiye. At least 15-20 days baad hi test kit se sahi pata chalta hai. Tab tak aaram karo aur achha khana khao.
Trust me, once the pregnancy symptoms actually start like the crazy morning sickness I had, you will know for sure! But in the first week, there are usually zero symptoms because the hormone levels are very low. Wait for your period date, then do a home test.
