please help!?

So yesterday, 11 dpo, I had a ridiculously faint positive. A week before, I had implantation spotting and cramping. I have had sore nipples, constipation, a little nausea, and have been exhausted. Yesterday, I had a little light pink spotting. Used a regular tampon and had a couple spots in the night. I woke up today and decided to use my diva cup to see if it was my period or what... a few hours later, I checked it and it only had a couple drops. But when I wiped, I had some brighter red blood along with two 1/2ish inch clots? I'm still very lightly bleeding but it's dark. I'm not really cramping and I normally have terrible cramps. Is it still possible that I'm pregnant? Or is this just my period?!
