Wa'alaikumussalam! Eh memang ada beberapa mums yang kena gaini, folic acid tablet tu memang boleh trigger nausea lagi teruk lah especially early pregnancy. Try taking it with food or masa malam before tidur, sometimes it helps reduce the muntah-muntah feeling. Definitely mention this to your doctor though, maybe dia boleh bagi alternative form like liquid or chewable, atau adjust the timing, jangan force yourself sebab the nausea akan jadi lagi teruk dan baby still needs the folate la. A few of us jugak ended up with different brands or lower dose awal-awal then increase later once morning sickness settled.
