Brown bloodclot??

(sorry it’s a big bloodclot) So I started my period Monday night. I am on the pill and did not take my placebo Sat, Sun, or Mon and Sunday my bf and I had sex (he didn’t pull out) and Monday night when it started it was brown, Tuesday it was red and back to brown Wednesday. I only bled on Tuesday when it was red and since it’s been back to brown i’ve been spotting. Last night I went to wipe and this is what was on the tissue. i’ve had blood clots before but never a brown bloodclot and not this big. should I be concerned?
