Could i be pregnant if my period barely lasted a day? im on birthcontrol and my last period lasted only 1 day with little discharge and only a few spots of blood.

If : If you are on hormonal birth control (such as the pill, nuva ring or Depo-Provera shot) and have been using it correctly, then you have a less than 1% chance of being pregnant. What is more likely is that you may be on a low estrogen birth control which can cause light or missed periods. If you are concerned about pregnancy, you should take a pregnancy test 1 week after the light period. Good luck!

Chance is small: if oral contraceptives are used consistently & correctly. However, you can take a home pregnancy to know.
