My body is being really weird

My body is throwing me off. I was supposed to start my period 3 days ago, but nothing. One thing I did notice is that I ovulated later than usual. I usually ovulate day 12-day 13 , but this month I think I ovulated day 17, which is pretty late.

Not getting my period is pretty weird, and I literally haven’t had sex In a while, so that shouldn’t be a reason
