My period seemed to be stop and go like it would skip a day then I would bleed again. After my period was over for 2days (today)I got some brownish blood and no more. But I took 2 tests. BothNegative?

Irregular. The irregular bleeding does not necessarily mean that you are pregnant. This could be just a hormonal fluctuation, stress etc. Give it two weeks, test again, then if periods not regular after two more cycles, see your gynecologist.
