4 days late period chances of pregnancy?

If you are 4 days late don't trip out so much. When you hit the 7 days late mark then start worrying. Anyhow if you are 4 days late and pregnant it would show up on a First Response 5 days sooner pregnancy test! So go to the store and get the first response test because it was on the news as the most accurate pregnancy test. If you get a negative result don't trip until the 8th day you are late and go get a blood test which the doctor will do anyway to find out what's going on to see if you are pregnant or not. Time will tell and so will pregnancy testing. Hope you get the results you want and I wish you the best! :)
