I have been to a scan today- am 6 weeks pg. Went because of spotting which turned into brown bleeding (mainly) for the last week with intermittent light cramping. She could only see a sac, nothing else. The sonographer said it could either be the start of a MC or just because it's too early to see. She said she's seen it go either way. I've had early scans before and seen a HB at this stage, so am not overly hopeful 
Has anyone any advice or experience on this, please? I am due to have a rescan in two weeks time- which feels like forever away
