Mommy, yan talaga ang common signs bago magpush ang baby especially with the back pain at legs, feeling ko rin yan noong ready na si baby ko, kaya excited ka na! But since may gastro symptoms pa din siya (the diarrhea at frequent peeing) at sobrang sakit, best talaga na i-check mo with your OB agad lang para ma-rule out kung hindi lang labor prep yan or something else na kailangan addressin, dahil 37 weeks ka na talaga so anything could happen anytime na. Your doctor lang talaga makakapagsabi kung bababa na or what's happening sa body mo, kasi bawat mama different, ha!
