Hi cantamend and presh I'm so sorry to hear you're both going through this at the moment. Hope you're both ok. 
It's so difficult and when you have the scan, you don't seem to be told much about what to expect which is scary. Then again everyone is different, so maybe that's why they can't say specifically what to do in terms of time off work etc.
Mine kind of happened the other way round, woke up bleeding at 6 weeks exactly (not very heavy, just like period), so I knew it was happening and went for scan to confirm, rather than having scan, and then waiting for the inevitable.
For me it was like a heavy period, bad cramps for the first day or two, then eased off. The bleeding never got that heavy, pads were enough, then passed a clot on about the 5th day and that was pretty much the end of it.
I think all you can do is look after yourself, cry, talk to your partner, and if you can get time off work it's good, even if physically you're ok, emotionally you're not. Unfortunately I was stuck in the middle of our busiest time in work and was only able to take a day, which was awful as I just kept nearly bursting into tears.
Wishing you strength through this difficult time
