Uy, congratulations sa second baby! But mama, lahat ng yan, yung back pain, pelvic pain, at pati yung minor leaking pag umuubo or biglang galaw, super common sa second pregnancy kasi the body changes differently, pero importante talaga i-mention mo lahat to sa OB mo sa next visit, lalo na yung pelvic pain kasi baka need ng specific exercises o support belt para makatulong talaga. A few of my mum friends who had similar pang-second baby issues, nabigyan sila ng pelvic floor physiotherapy or special prenatal stretches na sobrang galing, so don't feel alone sa experience na ito! In the meantime, make sure you're resting properly and maybe ask your partner or family to help with heavy lifting or bending down kasi clearly ang body mo ay nag-struggle na talaga with this pregnancy.
