TTC after miscarriage (TMI)

We found out our sweet little one no longer had a heartbeat on November 14th and on November 16th I had a D and C preformed. As of the 30th my doctor confirmed I had healed and was cleared for sex though for emotional reasons she suggested trying again in three months. We have since had sex and it hurt as bad as your first time. Is this normal? Has anyone else experienced this?
