Implantation bleeding twice 2 weeks before period

I've had light pink to brown spotting only when I wiped June 2nd, 2020 and on June 4th-5th, 2020 I again had it and it got a little darker but not too dark. Still was light pink and a tiny, tiny blood clot was in the toilet swirling in the water. Real small. I had small, mild cramps for those days I had spotting. 2 weeks before my next period which is next Wednesday on June 17th, 2020. I took a PT this morning around like 9:45 am after work. It was negative. I might've and hope I took it too early. My fiance said it could be my period trying to normalize after my nexplanon removal about 2-3 months ago. I plan on testing again next week. I've been having white, creamy, mild smelling discharge. I know its not an UTI due to not having a yeasty smell down there nor am I irritated down there or painful sex or urination. Please someone tell me I'm not losing my mind.
