Miscarriage- Meds or Surgery?

Sarah
Going through miscarriage at the moment. Was first time TTC in my 30's and conceived after only 3 months. Sadly 7 week scan showed slow development and slow heart rate. HCG not doubling and scan at 8 weeks showed no heartbeat and no further development. Light bleeding for a week now and had meds inserted in vagina today to bring on miscarriage. Another appointment in 3 days to discuss if further meds or D&C will be needed. 
Would love to hear others' stories of either procedure and whether people have been successful next time round. Would like to avoid the surgical procedure but at the same time would like to move on and try again before too long. Feeling heartbroken and confused and would love to hear from others x
