Clots or something else?

Kayla
So the dark red clot happened a week ago... My period had ended a few days prior. I don't usually spot or clot once it ends. But I did start a new BC the same day I started my period. This second clot that's almost grey in person , but also a translucent light brown. Just happened now. Okay, so the day my period ended I was spotting a pink/orange blood. Very little of it. My first thought was implantation bleeding. But as I stated I'm on birth control... So I shook it from my mind. I continued to spot here and there the past two weeks. But it was only pink once. Now I have been pregnant before but never had any implantation bleeding. I sadly miscarriaged... I've been cramping and spotting for two weeks now. And with my miscarriage the bleeding and clotting was heavier, thicker and bigger. The cramps were more intense than the ones I have now. But that miscarriage also took two weeks. I'm just scared of what's going on. I want to get advice before I worry too much. I will call a doctor if suggested. I usually never have any discharge of any color when I wipe it on my underwear ever. So this is why discharge of any color is disturbing for me.
