i just want to try again..

I just miscarried for the second time on sunday 10/1 i was 7 weeks & 6 days about to be 8 weeks. My doctor denied me of a D&C; saying i would pass on my own by time the D&C; comes. I was irritated because I've gotten the D&C; before & my main reason for wanting is so i mentally wouldn't have too see "all that" & my fiance & i want to try again immediately.. anyways i ended up passing on my own tuesday night after leaving the e.r from excessive bleeding. its thursday im still spotting. i also really want to try again & am so impatient & want to get pregnant. i do not want to wait til my next period & just want to know if its bad to still have unprotected sex while pretty much still going through a miscarriage?
