Need advice! Were your cycles abnormal?

Hilary
So, I'm coming up on 4 years of casual TTC.  My doc recommended clomid.  I hate medicine.  So I'm trying to avoid but will probably give it a try. I'm wondering, my cycles are ALWAYS 28 days and super normal, so what are the actual odds I'm not ovulating? Husbands SA was low normal, and we have a healthy oops baby that is 5.  Figures!  🙂
