6+3 spotting/coloured discharge ? 😞

Help… or advice.

No sex since I found out I was pregnant.

Went for a transvaginal scan Sunday morning. Next day I had spotting that was very light pink and only when i wiped and I only had it a couple of times! Today it’s more like this, more frequent and I have had mild period pains.

The scan on Sunday showed a sac measuring 11mm and a yolk sac, but nothing more. I go back Friday for a repeat scan. But wondering wether to contact the EPU tomorrow and ask for a scan a bit sooner.

Am I over thinking? Could this be nothing to worry about?

Thank you. Xx
