Uy, I totally get your worry, low BP and hemoglobin during pregnancy is scary talaga, lalo na first time mom ka pa lang! A few of us mums have dealt with this, and honestly, this is something you really need to discuss with your OB kasi it can affect you and baby, pero the good news is manageable siya with the right guidance. My friend's BP dropped around her second trimester din, and her doctor adjusted her diet (more iron-rich foods, tumaas ang beef and spinach intake niya), told her to drink lots of water, and rest more, check din if kailangan mo ng supplements. The key talaga is regular check-ups with your doctor para ma-monitor, at wag mo silang-silangin ang symptoms like dizziness or feeling faint, okay? Kaya mo yan, mama!
