Ay, alam ko yan, leg cramps talaga ang common na nangyayari especially pag pregnant or postpartum, kaya hindi ka nag-iisa! A few of us moms experienced the same pag third trimester or after giving birth, at sobrang sakit talaga when it happens. Usually it's related sa calcium, magnesium, or dehydration, pero para sure, mas better na check mo with your OB or doctor para malaman exactly kung ano ang cause at ma-rule out anything serious. In the meantime, try stretching before bed, stay hydrated, at warm compress helps din sa amin, pero yun, let your doctor confirm pa rin para peace of mind mo.
