I had this when I was 9 weeks pg (when obvioulsy the risk of something going wrong is still quite high) and I was really worried. However my Dr said it won't affect the baby, just might be worse for you than it would normally be because any nutrients that your body does have are basically being used by LO! I was in bed for two days, I felt dreadful. If you have a temperature with it (which I did) then you need to take paracetamol to make sure it is controlled. Other than that, just take as much fluid as you can and sleep as much as you possibly can. Also don't rush back out and about afterwards, take it easy becasue it will leave you feeling wiped out for a few days and you mustn't overdo it. I feel for you, I felt so wretched when I had it!I hope you feel better soon XX
