Infertility but have kid(s)

Cece

Anybody infertile and recently been diagnosed of infertility but already have a child or a few children? If so please tell me what it’s like because I am starting to think I’m infertile. Hubby’s sperm count is good the last time he went to get an analysis. Good swimmers. Both had a child in the past. Don’t know what’s wrong with me other than maybe I am infertile. Please help? What should I say to my gynecologist?
