Implantation bleeding?

Amber

I'm 13 DPO, started light bleeding yesterday was pink and rusty red mixed with clear mucus. Have had some stringy clots mostly. Thought maybe my period was just light on day one, but by the end of day 1 I'm usually going through 6 pads and have to double up with a tampon that is typically SOAKED to the tip. I'm having non of that, I'm having some light cramps, usually they're do bad I'm sweating and miserable. Usually I'm inhaling 7 chocolate bars and bloated. I'm not have any of that, I'm my 29 years of life my period has never been so sparse. We had sex, my partner and I every other day during my entire fertility window. So, could it still be implantation bleed? I'm nauseated, feel like the room is spinning sometimes. And my nipples are tingley, sometimes briefly sore. Which has never been a symptom for me. They're also a little bigger. So, my question is, can I have small clots and still be having implantation bleeding? Or is it probably my period? I feel really different but worry I'm psyching myself out. I will update 5 days from now. Also it's about when my period was due but I'm a 22 day cycle and it did start 12 dpo. So idk that may be typical for me.
