Bleeding in early pregnancy. Confused :( please help!

I bled red blood for one day Friday and then it stopped and nothing in the pad overnight since then. Just when wipe. It went brown and very light and stopped yesterday.

I have done another test just now to see. I wanted to see if the lines have got darker but cant see much so I'm worried?

I'm in limbo land as the early pregnancy unit aren't calling me till tomorrow. Hopefully they will let me come in for a scan when speak to them.

Last miscarriage at 5 weeks had few days of heavy bleeding.

Bottom pic is today and top pic was Saturday.

Period was due last Wednesday and didn't come which was when I tested as well!

Thank you xx
