Is my cycle longer? Or an I 6 days late, AGAIN?

[hyacinth]

hey ladies,
has anyone else notice since TTC that they're cycle length has increased? It was a solid 33 days for a full year. Now it's suddenly 39 days.

Any ideas why?

One theory I found in a different forum on this site was B6 Vitamins... maybe... but i'm not taking a B6... i'm only taking the Multi.

Thanks sooo much! your ideas mean alot to me!
