Is there complications with trying again right after miscarriage?

Maritza

I currently lost my baby at 8 weeks. I had seen the heartbeat twice and one night I felt strange. I went into the ER and there was no heartbeat. I was devastated. I didn't have a D&C.; I'm wondering when we can start trying again. Doctor told me 3 months, but that seems too long! Is there complications in getting pregnant right away after a mc?
