TMI SORRY IN ADVANCE I KNOW ITS GRAPHICAL!

Again I apologise I know it’s TMI and too graphical....

So I got what I thought was my period 4 days ago and it’s been on and off since. When I say on and off I mean no constant flow throughout the day and I only really leak when on the toilet or I stand too much.

I have had the implanon in my arm for a month and this is my first period since.

Tonight as I was on the toilet, this came out and now I’m kinda freaked out! Could I have been pregnant and I’m having a miscarriage?

Or is this normal with the implanon? I’ll see the gp tomorrow 100% to find out what’s going on but in the mean time had anyone experienced this?

I usually get clots during my period but never this big.
