my periods are usually clockwork, I always come on my period cd28/29. I’ve never been this late before, I did a pregnant test yesterday (cd31) and it came back negative. What is the likelihood that I am pregnant or my cycle is just out of whack this month? This is the first month in a while that I haven’t been tracking my bbt as we wanted to take a break from it all, so I don’t know for sure when I ovulated
