Hi there. Welcome. The time to take a pregnancy test is when you were expecting a period. do you track the length of your period? Do you have a certain day you would expect it on? Example, my period is generally every 28 days. Day one of my period begins that cycle. And then on day 29, a new period starts, so my cycle equals out to 28 days. This helps me know what day the following month my period is 'due'. If that day comes and goes with no period, then this is when I take a test.
The nausea and fatigue wouldn't quite happen so soon if you were pregnant.
Your timeline is a bit hard to follow. You had your period and still took the test?
