Don't go into work - I am in the same position and was worried about work but my boss was very understanding. You need to be at home in your own comfort and surroundings - don't add anymore pressure to yourself.
I also understand about feeling like you have failed as I feel exactly the same way - I am trying to get through by thinking it just wasn't meant to be and that its all part of some bigger plan (I appreciate how completely corny that sounds).
I'm 6 weeks pregnant and have been bleeding throughout. After a god scan on monday with a heartbeat, I have been bleeding far more heavily with clots, and since yesterday, awful pain.
I have another scan tomorrow morning (my birthday, how lovely), and I'm expecting for it to be bad news.
I phoned in sick on tuesday and yesterday (having got advice to do so from the epu). With things getting worse yesterday I phoned in sick again today. I have a 2 hour commute and couldn't face the prospect of bleeding heavily and being in work and hours from home.
I'm seeing my gp shortly, as if I have tmw off too I'll need a sick note. But I rarely have time off sick, this is the first time in 4 years I've need a sick note. I feel awful for going to the gp simply to get signed off work.
Am I being silly? Am I justified in taking time off work? I don't want to waste gp's time but I really can't face travelling into and being at work.
I'm taking this so hard as it's my miracle baby. I was due for ivf when I find out I was pregnant. Now I just feel like I've failed my baby and my husband. I really can't cope with the idea of losing it.
