[BRANDY2012]

Hi my name is brandy and my last cycle was on July 3rd 2012 and ended on July 8th 2012... my next cycle wasn't due until July 31st 2012 but I never got it... it is currently August 20 2012 and still haven't seen it... I took a pregnancy test around August 8th and it was negative... I haven't took anymore since then... me and my boyfriend always have unprotected sex and I'm not on any birth control... we're trying to get pregnant... yesterday as in August 19th 2012 we had sex but afterwards I starting spotting and cramping like I was getting ready to start my cycle (it was fairly rough)... so I got in the shower and put on a sanitary napkin and for the rest of yesterday and until now August 20th 2012 no bleeding at all... the napkin is clean... spotless... but I'm still having backaches and stomach aches like I'm cramping... HELP!!
