Help! Period or implantation?

Hello, Ladies. Yesterday, I was two days late for my period. I got worried since I’m experiencing cramps for a couple of days and my breasts are sore. Since it was already two days late based on my cycle tracker, I took a pregnancy test and it turned out negative. A couple of hours after, I started bleeding. It’s only very light compared to my regular period. However, it suddenly stopped last night, and I am bleeding just a little. Again, just light flow. I only changed pantyliner twice since yesterday since I wanted to check how much I am bleeding. It didn’t even fill the pantyliner, maybe half. I have an irregular cycle. Last cycle it was 34, before that it was 32. I am not trying to get pregnant. I’m worried that it can be implantation bleeding because I should have a heavy flow right now if it’s my regular period.

The photo below is my second pantyliner. The first one has a lot more than that.

Should I take another test again? If yes, when?
