Confused 🤷‍♀️

Soooo.... I tested Saturday and got a faint positive, today I tested with a different product and got a negative and I started lightly spotting today. My boobs are sore and I feel really tired today, my cramping I've had for a few days have been like period but not quite. I ovulated late this cycle which makes me think maybe the spotting today is implantation bleeding. Chart below.. any thoughts on this ladies? THANKS 🙏🏼
