*graphic: Early miscarriage ..? :( graphic picture

I was trying to get pregnant , and I had just started to feel kind of different physically so I was excited but waiting for my missed period to take a test , well like a whole week before my expected period all of the sudden I start bleeding heavily , all evening the next day and then I see tissue discharge, grey pink with bright red blood... Is this a sign of an early miscarriage? I decided not to take the test cause I thought oh my period but it's so heavy and quite the amount of discharge. I'm very sad, I don't know if f I'm just freaking myself out but I've never seen tissue like that. The picture is only a fraction of what I've seen... Plus lots of lower back pain. And I felt very sick the second day of experiencing this... Beyond just period sick . Update: same symptoms have continued today. Miscarriages won't affect your fertility right ? I feel like something's wrong with me, I've gotten checked out before an told I was healthy but I am afraid of this happening again...
