For women only....a lil personal ques!?

ok....i was too embarrased to ask the doc but....i recently lost my baby/ miscarried and had to have a d & c done April 2 nd to be exact...first off im still spotting ..barely enough to have to use a thin pantiliner but for those of you who have gonethrough this...how long will it take to completely stop? My doc already put me back on bc (Nuva Ring) but Im still spotting...its driving me crazy. Also, Im wondering how long after a d & c is performed do I have to wait before douching...Im a bad hygeine freak and this is dricing me nuts..lol...pls help
