Am I letting my anxiety get the best of me?

Okay long story
So before my most recent period which ended a couple days ago, my boyfriend and I had protected sex with a condom. This lasted five minutes, he didn't ejaculate and we checked the condom for holes. Pretty sure I wasn't fertile.
The only thing we did in my fertile window was I gave him a blowjob and I know I can't get pregnant from that.
Anyway my period came on time and it was lighter than usual. It lasted the normal time but was just lighter. The blood was still bright red and not pink or brown.
I had been worrying myself sick that I was pregnant. I was googling symptoms and everything.
I ended up taking a test to ease my mind at 19dpo and got a clear and fast negative with no faint lines.
Now it's after my period and my back still hurts, I'm bloated and I'm having pains down there.
Could I be ovulating? My cm is very watery and clear. Could all this be in my head and from worrying? 
I have an anxiety disorder so that doesn't help.
