Aww alam ko yan feeling, sobrang nakakaworry talaga lalo na first time mo! A few of us mums went through the same situation, and honestly ang best thing is regular check-ins with your OB kasi ang pelvic measurement at baby's size ay kailangan closely monitored para alam ninyo kung safe talaga ang normal delivery for your case. Aside from walking, pelvic exercises like squats and cat-cow stretches helped some of my friends, plus staying active, pero always cleared with your doctor muna talaga, lalo na kung may risk factors. The CS scare is real, but remember your OB is looking out for both you and baby, so whatever decision comes up, it's for your safety, not to scare you. Sending you strength, mama!
