Help! Is this implantation bleeding? TMI

On feb. 5th, I had protected sex with my boyfriend. We used a condom. He actually didn’t cum inside the condom and I finished him off with oral. I understand there’s a risk of precum but in that evening, we did not have any sort of unprotected sex. On feb. 9th, I experienced some spotting. Then on Feb. 10th, I had more bleeding and it had small blood clots. Yesterday i bled some more red, then it stopped in the evening. Now today, it’s brownish red. Last month, I took plan b and my period came early. Experienced heavy bleeding and lots of blood clots. Now, the month after, which is now, my period is being weird! Am I pregnant? Can someone please give me their input? Thank you.
