Miscarriage? TRIGGER WARNING GRAPHIC IMAGES

Lili

hey guys I just need some help figuring this out. so my period was about a week and a half late and I was having really sore tender breasts and some weird acid reflux things. but about two days ago I started what I thought was a period but ended up being very clotted and heavy. I took a pregnancy test today and this is what I got is it possible that I am having a miscarriage? Also attached is a picture of one of the clients that I had in my pad.
