Is this long normal?

Brittany

My periods used to be pretty regular/ normal. Now my body has decided that I have one month of no period and the next month with a period. I KNOW I ovulated at the beginning of July (I was testing to make sure I was ovulating at all to see if I needed to report back to my OBGYN that I don’t ovulate every month). I missed my period by a whole week and took a pregnancy test today to see what was going on. Still, negative. Am I pregnant and just don’t have enough of the hormone yet? Last time this happened I had spotting in my normal CM, but this time around I was REALLY dry. No spotting whatsoever. And I’ve been getting vaginal pain, too.
