is this a miscarriage

It's about the size of my pinky nail, not very big but larger than normal blood clots. My period was four or five days late and when I did start bleeding, it wasn't like my normal heavy dark red period blood. I've had sex about three times with my bf (withdrawal method) the two weeks before my period was supposed to arrive. I started thinking I was pregnant when my period wasn't coming and I had yellow discharge instead. I didn't get to take a pregnancy test yet bc I was gonna wait until the bleeding stopped to take it. Since I thought it might have been implantation bleeding. The picture isn't the best quality but it was a red shaped curved string thing more thicker at one end and had clearish thin skin around it. Sorry I pooped at the same time I took this lol. So I had to crop it.

Update: I don't get cramps on my period which might explain why I didn't have cramp stuff for this thing. I was queasy earlier in the week, very fatigued and weak and with vaginal pain but now I feel nothing but I keep on bleeding non-light amounts of blood. Maybe it was a very early miscarriage (I read online that very early miscarriages are mistaken for periods) or a late weird period. Thanks tho to the people who tried to help on this ^_^
