Hi,
The best is to seek professional helps. It could be due to your distress. My gynae told me before any distress arises from mc incident could worsen a person condition, physically and mentally. Why don't you talk to someone you trust the most or even your gynae. May be they can help.
All the best and hope you are fine.
beehappy is right. You said only your bf and you know. That is the key. I think you need to talk to someone professionally and work through the feelings you are having.
