AF getting later and later since TTC

Macey
For the past 4 or so years my period has been spot on, not even a day late. My husband and I have been TTC since August of last year and nothing so far, but within the past 3 months my period has been coming later and later, it is the weirdest thing. Has anyone else noticed this? I went from a 28 day cycle to now 32 day cycle but every month it goes a day or two longer, I know it doesn't seem like much but to me it is because like I said I am never late. Has anyone else noticed this since TTC?
