Obimin - multi vitamins

Hi mummies, seeking yr tghts on my concerns. Im on my 14th weeks and its has been close to 2weeks that ive choose to not take obimin. Typically bcoz i felt that every time i take tbe obimin, im experiencing with nausea, fatigue, morning sickness and its kind of bothering me. Ive highlighted to a gynae before and was adv to take it only at night to feel lesser side effects. Bt it proves me wrong coz the side effects kicks in d nxt morning. I am partially guilty for nt taking it coz im on a high risk pregnancy bt taking it is taking a big toll of me. I feel so down and tired. Nt taking it, im eating prettt well, up & about doing daily routines etc. Is there anyone who choose to not take obimin? What are the alternatives food/fruits i can replace with?
