3 days late, no period, negative tests...

Shaylee

Hello I’m 20 my boyfriend and I had unprotected sex my last two fertile days, well now I’m 3 days late, no sign of a period, but... all test come back negative. I took 3, 1 each day before my missed period and 1 the day after my period was “supposed” to start. They’ve all come back negative. Idk what to think or what.. has anyone ever had negative tests after your missed period and are pregnant? TIA🙂
