I am four days late on my period I took pregancy test they are all negative what should I do I feel pregnant.

First at a few weeks normally you don't "feel" anything but some women say they do.

First of course many women are late or early 4 days all the time, it does not come exactly as I am sure you know

You wait another week, and if still no period or just spotting, you do another test, make sure it is always from the first urine in the morning, not latter in the day.

If you are still late after a couple weeks, it could be an infection of some sort and you need a doctor check up

Don't woory, sometimes in a sudden change or something your cycle can change, I'm 8 days late right now, but I'm not pragnent. If your like 1 month late and still not getting anything then go to the doctor or take another test, but don't worry ^.^
hope this helps<3 goodluck(:

Pregnant :P ***
