Hmmm.... Morning sickness during pregnancy is unavoidable, but you don't need to take several days off to cope with it. Im 4 months pregnant and still working. I had morning sickness as well. Nevertheless, i dint let my boss or teammates know im expecting. Now when i think back i dont know how i managed that... but it's possible for pregnant women to make their condition an excuse to not work. I worked just as efficiently as anybody. We are employed to work and if there is no output from our ends, i dont see any reason why our employers should still keep us. Pregnancy doesn't mean chilling out for 9 months. If you find it so difficult to cope, it's better to stay at home. This is my opinion.
