Question

My hubby and I have been together for 8 years.. We have always had sex unprotected... And I've Never really paid attention to my fertile times.. But I'd assume I'd hit a fertile day within the 8 years of us being active.. I've never gotten pregnant before.. I'm scared something maybe wrong especially if my periods are normal.. Just becuase your periods are normal does that automatically mean you ovulate? What does clomid help with?
