Hi. I just have a question, so I have prenatal vitamins that I used to take but it smells like fish , so I asked a doctor for different one, now I start to use those for two days and I feel like I haven't got sleep since I start to use the new prenatal vit, so I switched back to my fish oil again. But its really not pleasant to drink cause of the smell and after taste effect so I took the nee prenatal vit again. Now my question is, is it gonna harm my baby if I switched prenatal vitamins? But not often tho I did it for only once or two days.
