It is very possible, some Dr's say you are even most fertile after a miscarriage. Sept 14/2010 i miscarried, Oct 21/2010 pos pg test!!!! And if you feel up for it, you can ever try again! Good luck!
It's not usually possible when I miscarried my doctor told me you wouldn't for 60-90 days and they don't recommend you have sex for a couple months due to getting an infection that it takes time for your body to heal. I would wait just to be safe. Good luck
