I had unprotected sex on june 8th 2013 i am on birth control and even took the morning after pill, on June 27 i was suppose to start my period and i had just started spotting on June 24th so that friday i took a pregnancy test it was postive and then i went to the doctors and took a urine test and it said positive they told me since i had two positive that a blood test really isnt necessary. So saturday June 28th i woke up at 11:40 pm with blood everywhere when i went to the bathroom it calmed down and the next morning woke up to more bleeding and clots in my stool. This has not stopped for 3 days now still heavy and still cramping. I am suppose to go get a blood test but would could this mean
