This is my 2nd pregnancy and was very sick with DS1 but managed to work but this time round the exhaustion and constant nausea (only actually vomit a couple of times a day)is really getting to me. I have had 1 week off work and feel guilty but can't imagine going back feeling like this. Am hoping that like the first time the sickness will stop at 13 weeks & I will be able to get on with life..
