Aw, yan yung ligament pain na common talaga sa third trimester, lalo na pag umabot na tayo ng 35 weeks, a few of us moms went through the exact same thing, parang may tumalon sa singit when we'd stand up or walk! But honestly, since it's on the right side at mataas pa, mas okay kung i-mention mo ito sa OB mo during your next visit para sure na walang ibang concerns, kasi first time ka pa at better safe than sorry talaga, sakit na paired with movement changes ay worth checking out.
