Hiya, and sorry to hear what you've /you're going through
I was told i'd get one from my doctor, and i did. The hospital send your notes over anyway so he'll be aware of what happened. My doc was really nice and seemed to offer me as much time as i wanted but i ended up taking 2 weeks off in all. From the day i found out on my scan, and the week after i had my d&c.
I was given the advice from friends not to rush back to work as you can be quite fragile even if you think you're ok, if that makes sense.
I understand it can be difficult if your job is not so understanding, i was lucky that way, but in the end you just have to listen to you body and mind and do whats right for you.
You will feel much better soon, chicken, i promise...
ps. My boss also asked if i wanted people to know, and again from advice i was given from friends, i said yes. So, although not everyone did know, those who knew were very undertstanding and actually shared stories..you'd be surprised how many people suddently this has happened to! Also, my doc asked if i wanted to put mc on the sick line, i said yes to that too. Hope this helps, if any...xxx
