conceive shortly after D&C?

I had a miscarriage Dec. 28th, & had a scheduled D&C; surgery Jan 4th. I had unprotected sex the 26th, and he ejaculated inside me as well. it's been about 3 weeks post surgery. I hear I am very fertile after miscarriage & would like to know if anyone got pregnant shortly after miscarriage? #wouldvebeen13weeks
