I canceled my appointment, and my spouse reacted.

My menstrual periods are very irregular due to a personal reason, but I’m afraid to go to the gynecologist. I have had a bad experience in the past, which is why I canceled my appointment. When I told my husband about it, he reacted unbelievably and accused me of being irresponsible. But I can’t explain it; this topic is sensitive for me. What should I do?
