Alam ko yan, first trimester to second trimester transition is tough talaga, insomnia and body aches are super common kasi ang hormones mo ay all over the place, plus ang belly mo lumalaki na kaya uncomfortable ang sleeping position, yun ang experience din ng most of my mum friends. About the constipation, ganyan talaga sa pregnancy dahil sa progesterone, so it's good na pinigilan ka ng OB sa milk muna, pero try coconut water, fruits with fiber, at maraming water throughout the day, a few of us swore by adding prunes or psyllium husk sa diet. Best to stick with your OB's advice on the milk since she knows your specific situation, pero if ang body aches mo ay hindi gumaan or ang insomnia ay super severe na affecting your daily life, worth checking back with her din para ma-rule out ang other concerns at ma-adjust ang management.
