Early miscarriage ?

Sugu

I had all symptoms of pregnancy

Like breast tenderness sensitive nipples , bloating metal taste exactly five days after my ovulation on sep 10th and for the past couple of days I had lower back ache thought it’s a sign of implantation ; now yesterday I did a indoor stationary cycling for twenty minutes

After which today I got my periods with clotting

Is this a failure in implantation?

What should I do now ; plz help me out
