My last period was on July 6. I had unprotected sex with my boyfriend a week after my period but he pulled out before he ejaculated.I took a test and it was positive. Yesterday I started bleeding light and today I am bleeding with mild cramping, can something be wrong with my unborn baby or am I even pregnant

If you had a positive test, then mot likely you are. It is time to make a doctor appointment to make sure nothing is wrong.
