Could I have missed my ovulation? I started testing 4 days ago and been getting no LH surge even though I'm in my "fertile window" could I have ovulated early because I have a normal 32 day cycle? Could I be having a short cycle this month? I know you ladies don't really have the answers. I just needed somewhere to actually put my questions out in the open.
