So about a month and a half ago I had protected sex (condom) the night right before my period. I now am almost two weeks late and I have taken two pregnancy tests, both were negative. I recently started a new job, school, and my schools marching band, and also have been stressing about being pregnant. I haven't had any of the symptoms, but why am I this late? Both: last year I missed two periods at the start of school

Life style changes, stress can all make you late.\\

But also, you can not even start testing till you are 2 week late, so you are still testing too early. After you are about 15 days late, do another test, using only the first urine of the day.\

A condom has a 3 to 18 percent failure rate, so they are far from 100 percent safe
