Am I freaking out for no reason?

Summer

Good morning

I am driving myself crazy. So here's what's going on.

I had sex June 19th and again June22/23.

I have noticed a few things different in my body the last 3 weeks that are unusual.

1. Excruciating ovulation pain on my side/pelvic area. Usually felt on right side, but this tome it was on the left and way more painful than usual-if it feel it at all

2. This Tuesday I had the worst back pain I've ever had on the right side of my back. I could barely walk. Neither Tylenol or Advil relieves the pain for 6/7 hours. Laid on couch 100 different ways chair standing etc. didn't get relief until I took some oxycodone

3. I have been having sporadic tastes of metal in my mouth which I just learned yesterday could be a sign of possible pregnancy

4. Light bleeding brown and pink yesterday ( I never ever spot belt my cycle)

5. Today it seems to be bright red/maybe darker pink can't tell. Don't know if I have filled tampon yet I haven't changed it

6. App says my cycle should start today.

7. Posting my Analysis for cycling period

8. Took test this morning (digital) said not pregnant

9. It's only been 3 weeks today from the time I had sex on the 19th

Please help me someone
