Pregnancy during/after mc?

So I'm going through a miscarriage right now and I will be taking the pills so it can just be over already. Husband and I had in protected sex last night and I wasn't even thinking about it. I know the chances are slim but if we continue to not be careful will I get pregnant? I personally highly doubt it due to the fact that it took so long to get pregnant in the first place. We're wanting to try again but not until the doctor says to go for it.
