I would tend to agree with your mother, and take whatever time you need. Only a few hours ago relatively speaking, your OH wanted to bring you to A&E. you need time to heal not only physically, but emotionally I think you need it,
I used to get irrationally annoyed with the work dramas especially when I had spent the weekend caring for my dying dad - and some stupid git would be moaning about the lack of stationary supplies or a minor mistake someone else made.
It also depends on if anyone at work knows about your pregnancy and MC. Sometimes you dont want to face a sad topic in a work environment.
You have been through physical and emotional trauma, so be kind to yourself for a little while longer.
I am due to test/get my period on Tuesday. I had really sore boobs last week, they are grand now but seem to be a bit fuller still. That could just be pre-period though usually they are sore right up to my period.
I decided to do a bit of Hypnosis to relax and calm me - It worked wonders years ago getting me off the fags so I have "positive thinking" and "radiant health" on the ipod, and seriously contemplating getting a fertility/conception one - think I will search a few fertility forums to see if any recommendations jump out at me.
