Can TTC make your period come late?

I hope I don't sound like a newbie or anything but I have NEVER had a late period until my husband and I had started trying to get pregnant. At first I thought it was the extra stress but I'm really not stressed, I'm a very chill person. 
What's the deal? (I'm usually only late by a couple of days but like I said for the last 9 years it's been right on schedule)
