Blood in Discharge - 18 weeks

Taran

So sorry about the TMI photos but needed some assistance on whether this is anything to worry about.

I've spoken to MW but she hasnt seen these as when I spoke to her few days ago it was just brown discharge, whichever she put down to being normal. However today and yesterday it has been like this.

I also have some cramping and have had lower back pain pretty much throughout however worsened over the past few days.

Help!
