Ginger might work on mild nausea, but if someone has got the point of saying they can't cope, I doubt ginger will do a think. I know people mean well, but it literally sends me into an internal rage when someone suggests it to me. I've been signed off work for the last month - do you not think I've tried f-ing ginger!???!! Arrrrgggh 

My GP has generally been very good, but the other day I vomited blood overnight and ended up calling the out of hours GP, who was concerned and I nearly ended up at A&E. The next day I called my GP to renew my prescription and mentioned the night before. Got a feckin locum who said "oh, do you really need all these pills" and "have you tried ginger?". I'm vomiting blood, for crying out loud!!!! Ginger?! Argh, he's lucky I was on the phone or I would have punched him then vomited in his face!
OP, you sound like you're in a bad way and you need to be taken seriously. Sometimes there's this impression that you're not sick, your "just" pregnant, and therefore need to struggle on as morning sickness is nornal. Pregnancy sickness can be severe. Even without the vomiting, the nausea can be debilitating. If your struggling, it ok to go the GP and discuss help. It is absolutely NOT admitting defeat. Honestly, check out the Pregnancy Sickness Support website and hotline, they will take you seriously. It can be awful, but there are things that can help a bit and it WILL pass. Let us know how you get on.
