So me and my boyfriend had unprotected sex June 16 ,2012 (Last day of my period) and I was wondering if there could be a possibility of pregnancy even though he didn't ejaculate. Also my periods last 4-5 days so I don't know if I could've been ovulating. It has been over a week and the only thing that seems not normal is the light yellow vaginal discharge . I'm worried . I know I did wrong but hopefully I don't turn out pregnant . Expert replies would be appreciated . Thank you
