Period blood clot, miscarriage or something else ?

I’ve never had anything like this come out before. I’ve only ever had dark red blood clots.

I started lightly bleeding 2 days ago and I was going to see my partner, so I just took 2 of the levlen pills which usually stops your periods yesterday.

And then today I woke up feeling very dizzy and nauseous. Later in the day I had normal discharge and then just before I got into the shower I had brown discharge/blood like stuff and then half way though my shower I seen something on my leg and it came out of my private area.

Me and my partner never use protection and he likes finishing inside...

I’ve had the implanon rod before for 3 years and then had it taken out and a new one out in. I’m on my second year of having the new one.

Should I be concerned about what this could be?.
