I ve recently started having unprotected sex. My boyfriend has been using the pull out method . I got my period last month on the 28th of July and we started having sex August 21st. So I thought I received my period on the 26th of this month but it s supposed to be ending and my urine is yellow but when I whip there s blood still. I m also cramping really bad, headaches, loss of appetite, bloatedness and lower abdomenal pain. All of which would of been gone after the first day I started my period, but symptoms don t seem to be going away. I know this sounds crazy, but could I be pregnant?
