So I am on birth control.. I had my period a week early.. Am I suppose to get my period the same day I'm suppose to strt? Like my last period was November 8 th and I got my period nov 29th and I'm not suppose I start until dec 8th so does this mean I'm pregnant ? I had unprotected sex a couple weeks before I had my period.. And I don't feel good at all.. My stomach feels nausea and I'm tired and moody and my nipples are darker
