I am 4 days late now, and I took a pregnancy test on the 30th and this morning and both have came back negative. I called my doctor and they said to wait a week and take another test, and it should come out positive then. But what if it never comes and I'm not pregnant? They said that unless my test comes out positive there is nothing to worry about, but it's not normal (especially for me) to miss or be late. Any advice?
