I am due to go back to work after a year's maternity leave. However I am also 10 weeks pregnant and really wiped out with nausea all the time. On my worst days I am probably sick 30 times in a day. I am exhausted and feel awful. My job is quite physical and around food and I just don't feel like I can do it. Would I be unreasonable to delay my return for a couple of weeks until it hopefully dies down? Last pregnancy it wore off at about 12 weeks but it also wasn't this bad. I can't shake the feeling that I just need to suck it up/ all women go through this etc etc.
