Hello ladies good afternoon. Three days ago I wrote to you guys asking for advice and opinion. Approximately two weeks ago I had unprotected sex. I was supposed to get my
period on Wednesday but no period. I decided to take a pregnancy test today  but it came back negative. Is it to soon to take the test! Or is it accurate.
