Has anyone gotten pregnant right after a d&c?

I had a d&c January 7th. Missed miscarriage is what they called it. I had bleeding the day of the surgery..after I went home to the next morning. Then for the next six days I had discharge. I then had unprotected sex the next night. We were told we could try again right away. I have my six week checkup next Thursday and I'm nervous we had unprotected sex everyday for the two weeks after my discharge stopped. I'm just wondering if it's possible to get pregnant this fast and will my baby survive?
