Should I be concerned? Ovulation bleeding? Or implantation?

Jessica

So I never have mid cycle bleeding EVER. I spot a day or 2 before my period and that's it, but now I have spotted light pink TWICE just slightly more than the amount shown and I have no idea what it means! Idk if I should see a Dr. Or what? Yesterday I was bloated and gassy and felt like lightning in my stomach and it just went away. Today I had mild diarrhea. I feel like its too early for implantation and too late for ovulation both of which I've never had as I've never implanted or been pregnant...
