Mornin sickness and working

around 5-8 weeks my sickness was terrible. i coukdnt even work.. now im 9 weeks pregnant n just got a job at CVS im so scared that i will get weak on the clock or hungry or feel the urge to vomit or faint. the store manager does not know im pregnant . i failed to mention it in the interview because i was afraid it was ruin my chances to get the job. 😢I just needed a job because this would be my 2nd child and i need the finances. Anyone have some encouraging words or advice from me ? Anyone works while dealing with morning sickness? how is it??
