Need help! Coming off Mini Pill TTC

Hi all,

I came off the mini pill On the weekend, the last pill taken was Friday 21st May. Had sex Friday, Sat Sun more than once.

However, I started cramping and brown discharge or blood appeared from yesterday (Weds 26th) cramping today but no blood. Would I put this as a period? According to the app my period is WAYYYY OVERDUE. But that’s because I had no period on mini pill and was on it for around a year so can’t remember my last period.

How can I input this so I know when I’m ovulating? I don’t know whether this is actual period or implantation bleed.

Can anyone help?!
