Please read!!

I took a test the day before my expected period, it looked negative. I started spotting pink on my expected period date, which is usual the day before I start.

I spotted off and on the next day, and then it turned red. It was on and off, but heavier than the previous spotting.

I don't think I've seen any clots at all, and it seems to be ended. There was old reddish brown when I used the bathroom this morning but that's it. I usually have a very heavy flow with extreme cramps, I had 1 very light cramp yesterday.

Could this be implantation? Should I take another test?

*included 2 ss, I recently started a new tracker app I prefer but don't have enough history on it yet so I included my other one as well
