Could I Still Be Pregnant?

I had, what I thought was implantation bleeding on the 19th and the 20th at 9 & 10 dpo. Both days it only lasted an hour, super super light pink then turned to brown. It never got any heavier or darker.

That Sunday I took a test and it was negative. The next day I took two more tests and both came up with what I thought were two vvvvvf positives. One was a frer and one was a mom med from amazon.

Fast forward to the 23 and AF shows her big ugly face, just as scheduled. I tested anyway and it was negative...

Could I still be pregnant or was I just randomly spotting and the two tests were indent lines?

I’ve been having some early pregnancy symptoms that never happen with my cycle; sore boobs, fatigue, lower back cramps, lower abdominal cramps.
