Weird cycle?

So I’ve posted before about my cycle breaking up all weird, but I’ll break it down again.

On October 29th I started my period. It was normal, a little lighter and my cramps weren’t as bad, so I thought everything was good. Then on November 16th I started spotting, which transitioned into what I thought was a period. I took a pregnancy test when I started bleeding just in case I was having a mmc, but it was negative. Then I took another one last weekend just in case and it was negative too.

So, IF that was a period that started on the 16th, I should be about to ovulate again, but I’ve been using my OPKs, and the test lines aren’t getting any darker. I just don’t understand what’s going on.

What are the chances I could be pregnant? Should I test again?
