Graphic Bloody Discharge Question

I saw this on my pad today, and while I thought I was starting my period, two lumps like this showed up with me pulling my tampon out, and the texture was different from my usual period blood clots. it was more sticky (because it would not easily slide off of my tampon, and there was almost a brainy-like substance attached to the two pieces that is pictured here. I used flash, so it looks darker than it is.) FYI: I had an abortion 2 months ago, and I'm on Trinessa. is this a miscarrage/final stage of abortion bleeding/or birth control side effects? Thank you.
