You can have sex as soon as the bleeding and discharge have stopped or after 2 weeks. This is the time which is given for bleeding to stop and uterus to heal properly. If you have any increased bleeding, do consult your gynecologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
If anyone is interested... I had my follow up after novasure and as you read my comment from the other day I was worried because my husband and I did not wait the two weeks before intercourse. The doc said no harm no foul. As long as there is no pain and no sign of infection the two weeks is just precautionary... You are good to go as long as you are very careful! No rough sex!
