How long after D&C and after the 3 month wait after getting shot did it take to conceive?

Hanna

Hello I just had a D&C yesterday and they are saying that the tissue didn't appear to be pregnancy tissue, they are running test but it is likely that I will need to get the shot for ectopic pregnancy. Has someone had something similar happen and after the 3 month waiting period was able to conceive again? I am worried I won't be able to again.
