Honestly one week is very early, home kits often cant detect it that soon. A blood test at a lab can pick up hcg a bit earlier than urine kits. For accuracy though, waiting till the missed period gives the clearest result.
I tried to find out in the first week and just drove myself mad with false negatives. The hormone is too low so early. Try to wait a little, I know the wait is torture but it really gives a true answer.
At one week there isnt enough hcg yet for kits to show reliably. Symptoms that early are also too vague to confirm anything. Best is a beta hcg blood test closer to ur missed period, the lab can guide on timing.
