Prenatal vs multivitamin

I recently had a MMC (first pregnancy). I had a D&C last week and am trying to get my body ready to TTC again. With my first pregnancy I was taking a multivitamin, my doctor said this was fine...but after doing some research I'm finding that there are many differences between the two. Do you take a prenatal or multivitamin? If you take a prenatal vitamin when did you start taking them?
