Should I be worried?

Ok we BD’d on dec 26 and 31st. The 1st was the last day I possibly could’ve ovulated. I started getting faint lines every morning this last week and a + digital yesterday complete with hormones, mild nausea, sore boobs, food aversion and heightened sense of smell. I thought implantation happened already on the 8th and wasn’t expecting any bleeding. Today I’m getting a tiny bit of pink when I wipe, my boobs are way less sore, and I’m not nearly as hormonal as I was. All the research I’ve turned up and my apps say I’m still in the window for implantation bleeding but this symptom drop has me worried I’m headed for a chemical. Has anyone else experienced anything similar? I know there’s nothing to be scared about yet just can’t shake this worried feeling.
