I'm a bit worried about my wife who's in her 7th week of pregnancy. She's been having a really tough time with vomiting and just can't seem to keep anything down. The doctor suggested she try Emeset 4mg, but after taking it, she's been feeling uncomfortable with some stomach pain and constipation. I looked it up online, and now I'm confused because there are mixed opinions about using it during pregnancy. Do you think it's safe for her to continue with this medication, or should we consider switching to something else?
