Period or Miscarriage?

First month on the pill

I am on the sugar pills now, last day of them on Saturday.

When I started the pill I shortly after had sore breasts and a little bit of spotting.

Then, after I started the placebos I had brown and light pink spotting.

Eventually I got what seems like a full on period.

This came out today though, is this just a period clot? I’ve never seen one like this before.

My period isn’t even that heavy.

I had unprotected sex with my fiancé finishing in me, but not until a week on the pill.
