I think that I may be PG. My period is always on time or a day early, I am one day late. I took a test yesterday and it was negative, does that mean that I am just late?

The standard over the counter pregnancy test will turn positive between 12 and 16 days after ovulation/conception. If the result is negative, repeat the test in 4 days and if it is still negative you are probably not pregnant unless you had an unusually late ovulation this particular cycle.
