Wa'alaikum assalam sis! Congrats on trying for baby number two, exciting! Honestly nutrition-wise, most of us just focus on the basics: take your folic acid religiously (really important), makan protein yang cukup, and jangan stress sangat lah because that actually boleh affect hormones. A few of my mum friends swear by tracking ovulation with apps or even yang simple-simple macam follow your body signals je, tapi memang kena consistent makan well and sleep proper. Other than that, just be patient with yourself, it'll happen!
