I'm 23 weeks pregnant and have generally been fine (had some evening morning sickness in first trimester, but little since 15 weeks). Over the weekend I've been feeling really unwell, physically sore all over and very lethargic. This morning at work, I was suddenly overcome with nausea whilst sitting at my desk and I'm currently lying on the floor of the disabled toilet as it's the only thing that makes the nausea and faintness go away. I've only ever called in sick twice in nearly four years (bereavement and suspected miscarriage early in this pregnancy).
My AIBU is firstly should I go home, and secondly is this to be expected at this point in pregnancy or should I be contacting my doctor? Midwife is shocking (still haven't met her and she doesn't answer her phone) so not sure who to ask for advice.
